Question

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.

 

Find the probability that she gets at least 2 cherry tomato seedlings. (round the answer to 3 decimal places)

 

 0.995 P(at least 2) = 1 – P(X = 0) – P(X=1)
1 – 15C0 * 0.4⁰ *0.6¹⁵- 15C1*0.4¹*0.6¹⁴
1 – 0.0000 – 0.005
= 0.995

Answer 1

Your formula is perfect!
