The probability that his outfit will be the black pants with the yellow shirt is 2/12.

<h3>What is the probability?</h3>

Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.

The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

Terry has 3 pairs of pants: black, khaki, and brown, and 4 shirts: yellow, red, blue, and white.

He does not care which colors he wears together. If Terry chooses one pair of pants and one shirt at random.

The number of black paints = 1

The number of yellow shirts = 1

The probability that his outfit will be the black pants with the yellow shirt

= 2/12

P( $r$ successes in $n$ trials) = ⁿ $C_{r}$ × $[P(Success)^{r}]$ × $[P(failure)]^{n-r}$

We have
$n=8$
$r=2$
$P(Success)=0.15$
$P(Failure)=0.85$

Substitute these values into the formula, we have
P( 2 success in 8 trials) = ⁸C₂ × (0.15)² × (0.85)⁶
P( 2 success in 8 trials) = 0.2376.... ≈ 0.24 = 24%
