If a seed is planted, it has a 40% chance of growing into a
healthy plant. If 101 randomly selected seeds are planted, answer
the following.

a) Which is the correct wording for the random variable?
Select an answer rv X= the number of
randomly selected seeds that grow into a healthy plant rv X =
a randomly selected seed that grows into a healthy plant rv X
= grows into a healthy plant rv X = the probability that a
randomly selected seed grows into a healthy plant rv X = a
randomly selected seed rv X = all seeds that grow into a
healthy plant rv X = the number of 101 randomly selected seeds
that grow into a healthy plant

b) Pick the correct
symbol: ? σ s X̄ N n X p μ =
101

c) Pick the correct
symbol: ? σ s N μ X̄ p n X =
0.4

d) What is the probability that exactly 34 of them grow into a
healthy plant?
Round final answer to 4 decimal
places.

e) What is the probability that less than 34 of them grow into a
healthy plant?
Round final answer to 4 decimal
places.

f) What is the probability that more than 34 of them grow into a
healthy plant?
Round final answer to 4 decimal
places.

g) What is the probability that exactly 39 of them grow into a
healthy plant?
Round final answer to 4 decimal
places.

h) What is the probability that at least 39 of them grow into a
healthy plant?
Round final answer to 4 decimal
places.

i) What is the probability that at most 39 of them grow into a
healthy plant
Round final answer to 4 decimal
places.
