What is the main drawback of seawalls? Hard structures partially hinder the recreational use of the coastal zone and can cause adverse ecological effects within the coastal zone. For example, when seawalls are constructed on eroding beaches, the erosion continues so that the beach in front of the seawall can become very narrow or disappear […]
What are the basic principles of scientific thinking?
What are the basic principles of scientific thinking? The Six Principles of Scientific Thinking. For a claim to be meaningful, it must in principle be falsifiable, that is, capable of being disproven.

What is the probability of getting at least one six on three rolls of a die?
What is the probability of getting at least one six on three rolls of a die? Attempt: Since there can be one six or two sixes or three sixes on three rolls, I considered separate cases and added them up. So (1/6)(5/6)(5/6)+(1/6)(1/6)(5/6)+(1/6)(1/6)(1/6)=31/216, but answer is incorrect as per book. What is the probability of getting […]
