Question
If P(success) = 14%, what is the probability your first success occurs on the 5th trial? Eight girls. Six boys. if randomly selected, the probability you choose one girl and one boy? If P(success) = 14%, what is the probability you have exactly 2 successes among the first 8 trials? If P(success) = 14%, what is the probability that out of 4 trials, you have at least one success? In a normal distribution, mean length is 10", standard deviation is 2". What is the probability the length will be shorter than 8"?Explanation / Answer
10.
p ( success) = .14
P( 1st success on 5th trial)
= P( 4 loss, 5th is a success)
= (1-.14)^4 ( .14)
= .0765
