If a seed is planted, it has a 75% chance of growing into a healthy plant. If 8 seeds are planted, what is the probability that exactly 3 don't grow?
According to Bernoulli Trials
Probability of getting r times success in n number of trials is equal to
*(Probability of success) r * (Probability of failure) n - r
Here,
Probability of success (Seed grows into a healthy plant) = 75/100
= 3/4
Probability of failure = 1 - Probability of success
= 1 - (3/4)
= 1/4
So,
Probability that exactly 3 don't grow OR exactly 5 grow
