Question

A box contains 6 red marbles and 4 white marbles. One marble is pulled from the box and not replaced. Then a second marble is pulled from the box. What is the probability both marbles are white?

1. 2/4
2. 4/10
3. 12/90
4. 16/90
5. 4/100

Answer 1

Answer: 12/90

Explanation:

Given that there are 4 white marbles in total among the total of 10 marbles, the likelihood that the first marble will be white is 4/10.

There are 3 white marbles and a total of 9 marbles in the box once the first white marble is drawn. Consequently, 3/9 of the time, the second marble will be white.

We may calculate the likelihood that both marbles will be white by multiplying these two probabilities together: (4/10) * (3/9) = 12/90.

So, 3 is the right response. 12/90.
