Question

If a seed is planted, it has a 54% chance of growing into a healthy plant. Let X be the number of seeds grow into healthy plants when 50 seeds are planted.

What is the distribution of X? X ~ B ( , . )

Please show the following answers to 4 decimal places.

What is the probability that exactly 24 seeds grow into healthy plants?

What is the probability that at least 24 seeds grow into healthy plants?

What is the probability that less than 24 seeds grow into healthy plants? What is the probability that between 20 and 26 (including 20 and 26) seeds grow into healthy plants?

Answer #1
