Question

1) The probability of snow if February is 0.2. For 6 randomly chosen years, what is the probability that exact 3 of them had snow in any order. Give your answer as 0.XX

2) If the probability of owning a dog is 20%, what is the probability of randomly sampling 10 people and finding that exactly 3 people have dogs. Give your answer as 0.XX

3) One possible reason why your data do NOT match to that expected for the binomial distribution is that the data:

are randomly distributed

4)T/F For this class, the probability of a rare event is one that has a likelihood of less than 5%. The answer is true: note that it is less than 5%, not 5% or less.
