Suppose that the probability a seed will germinate is 80%. what is the probability that 7 of these seeds will germinate when 10 are planted? a. 1.0068 b. 25.17 c. 120 d. 0.201

d. 0.201

Step-by-step explanation:

Given: The probability a seed will germinate = 80%

i.e.

Then probability of a seed will not germinate is given by :-

i.e

i.e.

By Binomial Distribution, the probability of getting r successes in n trials is given by :-

Now , the probability that 7 (r=7) of these seeds will germinate when 10 (n=10) are planted is given by :-

so, converting firstly the mixed fractions to improper fractions and then "adding".
