Question

A jar contains 6 yellow marbles, 4 black marbles, and 2 purple marbles. Two marbles are picked at random, without replacement. What is the probability of

selecting both yellow?

Answer 1

The probability of selecting both yellow is 5/22.

Explanation:

Given the number of yellow marbles = 6

Black marbles = 4

Purple marble = 2

Now find the total number of marbles in the jar.

Thus total marbles = Yellow marbles + Black marbles + Purples marble

Now insert the values in the above formula.

Total marbles = 6 + 4 + 2

Total marbles = 12

The probability of 2 yellow marble:

`= (6)/(12) * (5)/(11) \\= (5)/(22)`

Thus, the probability of selecting both yellow is 5/22.
