An archer has a 30% chance of hitting the
bullseye on a target. What is the
probability that the archer will hit the
bullseye exactly two out of five times?

Respuesta :

The probability that the archer will hit the bullseye exactly two out of five times is 0.3087

How to determine the probability?

The given parameters are:

Sample space, n = 5

Number of hits, x = 2

Probability of hit, p = 30%

The required probability is then calculated using the following binomial formula

[tex]P(x) = ^nC_x * p^x *(1 - p)^{n-x}[/tex]

So, we have:

[tex]P(2) = ^5C_2 * (30\%)^2 *(1 - 30\%)^{5-2}[/tex]

Evaluate the product

P(2) = 0.3087

Hence, the probability that the archer will hit the bullseye exactly two out of five times is 0.3087
