40:01:35 Assume the random variable X has a binomial distribution with the given probability of obtaining a success. Find the following probability, given the number of trials and the probability of obtaining a success. Round your answer to four decimal places. PCX 2), n6,p 0.3

Answer 1

P(X x)nc,(1 - p)"(p}" n-I

P(X 2) 1 - P(X2)

  

1 P(X 0) P(X 1)- P(X 2)

1-6c (0.7)0(0.3) - 6 (0.7)-(0.3)-6c (0.7)(0.3)

  

1 1(0.7)-6(0.7) (0.3)- 15(0.7)(0.3
