Explanation / Answer

Let x be the number of peas out of n peas having green pods.

a) The required probability is given by P[X=7] = 0.302

b) The probability of getting 7 or more peas with green pods is given by:

P[X=7]+P[X=8] = 0.399

c) We can conclude from part(a) that 7 is an unusually high number of peas with green pods as the probability is very high.

d) P[X=7]>0.05. Thus it crosses the threshold of 0.05. Hence it is unusually high. Thus option d is correct.
