If a seed is planted, it has a 80% chance of growing into a healthy plant.

If 8 seeds are planted, what is the probability that exactly 1 doesn't grow?

0.336

Step-by-step explanation:

Use binomial probability:

P = nCr p^r q^ (n-r)

where n is the number of trials,

r is the number of successes,

p is the probability of success,

and q is the probability of failure (1-p).

Here, n = 8, r = 7, p = 0.8, and q = 0.2.

P = ₈C₇ (0.8) ⁷ (0.2) ⁸⁻⁷

P = 0.336
