A binomial experiment has 4 trials in which p = 0.4. What is the probability of 3 successes?

Kaylis [27]

The probability of 3 successes is 0.0384

<h3>How to determine the probability?</h3>

The given parameters are:

Trials, n = 4
Probability of success, p = 0.4

The binomial probability is represented as:

$P(x) = ^nC_x * p^x * (1 - p)^{n-x$

So, the probability of three successes is:

$P(3) = ^4C_3 * 0.4^3 * (1 - 0.4)^{4 -3$

Evaluate the factors in the expression

$P(3) = ^4C_3 * 0.0384$

Evaluate the combination expression

P(3) = 1 * 0.0384

Evaluate the product

P(3) = 0.0384

Hence, the probability of 3 successes is 0.0384
