PLASE HELP it’s easy I know but I need help

Complete question :

70% of a certain species of tomato live after transplanting from pot to garden. Najib transplants 3 of these tomato plants. Assume that the plants live independently of each other. Let X = the number of tomato plants that live.

What is the probability that exactly 2 of the 3 tomato plants live?

You may round your answer to the nearest hundredth.

0.44

Step-by-step explanation:

Given that :

P(live after transplanting) = 0.7

Assume plants live independently of each other :

Number of tomatoes transplanted = 3

Number of potatoes that live = x

Probability that exactly 2 of the 3 tomatoes live?

Using binomial probability ;

p = 0.7

1 - p = 1 - 0. 7 = 0.3

P(x = x) = nCx * p^x * (1 - p)^(n-x)

P(x = 2) = 3C2 * 0.7^2 * 0.3^(3-2)

P(x = 2) = 3C2 * 0.7^2 * 0.3^1

P(x = 2) = 3 * 0.49 * 0.3

P(x = 2) = 0.441

= 0.44 ( nearest hundredth)
