Delvig [45]

Answer:

The correct answer is 0.15

Step-by-step explanation:

According to the given scenario, the probability is as follows:

X $\sim$ Bin (n,p)

Here

n = 8

p = 0.20 or 20%

Now this is a binomial probability distribution

$P(X) = ^nC_x \times p^x \tmes (1 - p)^{n-x}\\\\P(3) = ^8C_3 \tims 0.20^3 \times (1 - 0.20)^5$

= 0.15

Hence, the correct answer is 0.15
