What is the ratio of the number of favorable outcomes to the total number of outcomes in an experiment?
The theoretical probability of an event can be defined as the ratio of the number of favorable outcomes to the total number of outcomes in the sample space. For example, if a die is tossed, the probability of getting a 4 is because 4 is one of six possible outcomes.
What is the difference between favorable outcomes and possible outcomes?
Outcome – a possible result of an experiment or trial. e.g. When tossing 1 coin, a possible outcome or result is tails. Favorable Outcome – the result that is desired. e.g. Roll a 4 on a die → 4 is the only favorable outcome.
How many outcomes does a spinner have?
There are three possible outcomes of spinning Spinner A.
What is the probability of spinning a 3 on both of the spinners?
The probability of spinning a 3 is also 2 / 8 . Spinning a 2 and spinning a 3 are equally likely on this spinner because there is the same probability of each outcome occurring.
What is the probability of spinning a 3 on a spinner divided in 5 equal sections?
20%
How many possible outcomes can you have if you spin the spinner and roll a die?
There are 6 equally likely outcomes when we roll the die, and 4 equally likely outcomes when we spin the spinner. According to the Fundamental Counting Principle, when we roll the die and spin the spinner the number of equally likely outcomes is (6)(4) = 24.
When three coins are tossed how many outcomes will appear?
eight
What is the probability of getting 3?
Two (6-sided) dice roll probability table
| Roll a… | Probability |
|---|---|
| 3 | 3/36 (8.333%) |
| 4 | 6/36 (16.667%) |
| 5 | 10/36 (27.778%) |
| 6 | 15/36 (41.667%) |
What is the probability of rolling a 1 and then a 2 on a six sided dice?
Since there are six possible outcomes, the probability of obtaining any side of the die is 1/6. The probability of rolling a 1 is 1/6, the probability of rolling a 2 is 1/6, and so on.
When rolling two dice What is the probability that one die is twice the other?
6/36
What is the chance of getting 7 or 11 with 2 dice?
What about 7 OR 11? There are 6 x 6 or 36 options, all are equally likely, 7 occurs 6 times, so the chances are 6/36 or 1/6. 11 occurs 2 times so chances are 2/36 or 1/18.
What is the probability of rolling the difference of 1?
Let A be the event of getting the difference as 1. = 10. = 5/18. Hope this helps!
What is the probability of getting a difference of 0?
Answer: The probability of getting a difference of 0 is when the dice match.
When two dice are rolled what is the probability that the two numbers are have sum equal to 8?
365
What are the odds against rolling a sum of 11?

What is the probability of getting a sum of 15 if 3 dice are thrown simultaneously?
If three dices are thrown simultaneously, then the number of all the possible outcomes are 63 = 216. Let A be the event of getting a sum of 15 when three dices are thrown simultaneously.
What is the probability of rolling a sum less than or equal to 9?
With the usual assumptions (fair dice, fairly cast) each square has a probability of 1/36. Count the squares that have numbers less than 9 and multiply by 1/36 and that’s your answer.
What is the probability of rolling a sum less than 10?
That totals 8 combination out of 36 that could be ten or higher, so 8/36= 2/9. since I wanted less than ten 1-(2/9) = 7/9 probability of getting less than 10.
What is the probability of rolling a sum greater than 10?
1/5. Since there are a total of 6 x 6 = 36 outcomes, then the probability that the sum will be greater than 10 is 3/36 = 1/12.
What is the most likely score from throwing two dice?
Dice Roll Probability As you can see, 7 is the most common roll with two six-sided dice. You are six times more likely to roll a 7 than a 2 or a 12, which is a huge difference. You are twice as likely to roll a 7 as you are to roll a 4 or a 10.
