No, because the probability that 4 or more of the selected adults believe in reincarmation is less than 0.05

Explanation / Answer

p = 0.4

n = 5

P(X = x) = 5Cx * 0.4x * (1 - 0.4)5-x

a) P(X = 4) = 5C4 * 0.44 * 0.61 = 0.0768

b) P(X = 5) = 5C5 * 0.45 * 0.60 = 0.0102

c) P(X > 4) = P(X = 4) + P(X = 5) = 0.0870

d) Option-A)
