Answer:

24/225

Simplified: 8/75

Step-by-step explanation:

8 + 4 + 3 = 15

Since there are no replacements the denominator will get lower every time a marble is pulled.

First is blue which means,

3/15

The second is white,

8/15

If I'm not wrong you would multiply 3/15 and 8/15 and you get 24/225.

Simplified: 8/75

The probability that the first marble is blue and the second marble is white, that is P(blue marble and white marble) is 8/75.

What is the probability?

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.

A bag contains 8 white marbles, 4 green marbles and 3 blue marbles.

2 marbles are selected at random without replacement.

Total number of marbles

8 + 4 + 3 = 15

Since there are no replacements the denominator will get lower every time a marble is pulled.

The first marble is blue ; 3/15

The second is white ; 8/15

The probability that the first marble is blue and the second marble is white, that is P(blue marble and white marble)

=  3/15 x 8/15

= 24/225.

= 8/75
