Mimi plans on growing tomatoes in her garden. She has 15 cherry tomato seeds. Based on her experience, the probability of a seed turning into a seedling is 0.40. (a) Let X be the number of seedlings that Mimi gets. As we know, the distribution of X is a binomial probability distribution. What is the number of trials (n), probability of successes (p) and probability of failures (q), respectively? (b) Find the probability that she gets at least 10 tomato seedlings. (round the answer to 3 decimal places)

Answer #1

Given the probability of a sees turning into seedling is p=0.40

Let X be the number of seedlings that Mimi gets.

a) Therefore,

Where n=15 is number of trials,

p=0.40 is the probability of success,

q=1-p #probability of failure

q=1-0.40

q=0.60

The probability that she gets at least 10 tomato seedlings is given by:

### by using excel function:

"=BINOM.DIST(9,15,0.4,1)"

The probability that she gets at least 10 tomato seedlings is 0.034
