The probability that a randomly selected person agrees with a certain governmental policy is 46%.
Suppose five people are selected at random. Find the probability that at least one of the five selected
people agrees with the policy
Thank you for the opportunity to help you with your question!
using binomial probability
P = nC^k *p^k * q^ (n-k)
p=0.46 0r 46%
q= 1-0.46 = 0.56
P = 5C^1 *(0.46)^(1) * (0.56)^ (5-1)
probability that at least one of the five selected people agrees with the policy P = 0.22 or 22%
