Sam chose one marble from a bag containing 2 red marbles, 3 white marbles, and 10 black marbles. Find the probability that the marble sam chose was black?

what is the answer to the problem.

P (black) = 2/3

Step-by-step explanation:

We need to find the total number of marbles

2 red marbles + 3 white marbles + 10 black marbles = 15 marbles

To find the probability that Sam chose a black marble, we take the number of black marbles and divide by the total number of marbles

P (black) = black marbles/total marbles

= 10/15

Divide the top and bottom by 5

= 2/3
