How many socks would you need to remove from a drawer contains 10 blue socks 15 black socks and 5 red socks to ensure that you have at least 2 matching socks?

How many socks would you need to remove from a drawer contains 10 blue socks 15 black socks and 5 red socks to ensure that you have at least 2 matching socks?

Three socks remains the answer. Any two socks form a pair of socks, so you would only need to take two socks to ensure that you have a pair.

How many socks do I have to remove in order to guarantee that I remove 2 socks of the same color?

The correct answer is indeed “4”. You have three different colors of socks in the drawer. The first three you pull out COULD each be a different color… that is, you could possibly have one white, one black, and one red sock. The next one you pull out HAS to match one of those colors, thus giving you a pair.

How many individual socks do you need to pull out of the drawer to be sure you have at least 1 matching pair?

four socks

How many socks I must pull out of the drawer to guarantee that I have a matching pair?

11 socks

What is the smallest number of socks you must take out of drawer if there was a 40 watt bulb?

The answer is ONE PAIR. If you are like most people and have rolled the socks together in pairs when you put them away, there is no guessing and you just grab a pair of socks.

How many socks will be there in 50 pairs?

Although six white socks and fifteen red socks gives us a 50:50 solution, there are an odd number of red socks. The next solution at {35,85} is also odd, as are the next few … We have to go all the way to 59,992 white socks and 144,834 red socks before we get our first answer with an even number of each pair of socks.

What is the least number of socks that must be selected?

The minimum number to get a pair of socks is two, because a pair is two. If you meant to ask maximum, then it depends on what is meant by correct pair. If correct just means a matching pair, then 3 is the maximum. If the first is red, then the second will either match red, or be white.

How many pairs do 32 socks make?

16 pairs. Have these irrevelant extra characters.

What is the probability that you get two socks that match?

The probability of picking a pair of white socks is also 1/2 of 11/23, meaning in order to get the probability of picking any matching pair, you add these two together. The final probability of picking a matching pair of socks is 11/23, or 47.8 percent.

What is the probability that we get at least two socks of the same color?

Picking the first sock of the two with the same color has the probability of 2/6, and therefore picking the second sock with the same color has a probability of (2−1)/(6−1)=1/5 respectively.

What is the probability that two randomly selected socks have a different color?

2 Answers. From 10 socks you are choosing 2, so you have (102) possibilities. And to two socks to be different color you have to pick one blue and one white so you have (51)(51) possibilities.

What is the probability that you do not get a blue pair of socks?

If you pick one sock, the probablility is 4/12 that it’s blue and 8/12 that it’s not blue. So the probability that the first sock is blue is 4/12 = 33%. If the first sock is blue, then you now have 3 blue and 8 not blue socks.

How do you store socks in a drawer?

What you’ll do:

1. Lay the first sock flat horizontally.
2. Cross the second sock on top vertically.
3. Fold cuff from the bottom sock and tuck into the toe. It’s as easy as fold, tuck, fold tuck. Anna De Souza. Shop the look: Bombas socks.
4. Do the same for the top sock to secure it all together.

How do you find the probability?

How to calculate probability

1. Determine a single event with a single outcome.
2. Identify the total number of outcomes that can occur.
3. Divide the number of events by the number of possible outcomes.

What is the probability formula?

Formula for the probability of A and B (independent events): p(A and B) = p(A) * p(B). If the probability of one event doesn’t affect the other, you have an independent event. All you do is multiply the probability of one by the probability of another.

What are the 5 rules of probability?

Basic Probability Rules

• Probability Rule One (For any event A, 0 ≤ P(A) ≤ 1)
• Probability Rule Two (The sum of the probabilities of all possible outcomes is 1)
• Probability Rule Three (The Complement Rule)
• Probabilities Involving Multiple Events.
• Probability Rule Four (Addition Rule for Disjoint Events)

What is probability and how is it calculated?

Probability is the measure of the likelihood of an event occurring. It follows that the higher the probability of an event, the more certain it is that the event will occur. In its most general case, probability can be defined numerically as the number of desired outcomes divided by the total number of outcomes.

What is the probability a randomly selected?

For example, if you were to pick 3 items at random, multiply 0.76 by itself 3 times: 0.76 x 0.76 x 0.76 = . 4389 (rounded to 4 decimal places). That’s how to find the probability of a random event!

What are the 3 types of probability?

Three Types of Probability

• Classical: (equally probable outcomes) Let S=sample space (set of all possible distinct outcomes).
• Relative Frequency Definition.
• Subjective Probability.

What is the probability that a randomly chosen man is a smoker?

What is the probability of a randomly selected individual smoking? Again, since no mention is made of gender, this is a marginal probability, the total who smoke divided by the total = 31/100 = 0.31.
