Question

Ajar contains 3 red, 4 blue, and 5 white marbles. What is the probability of drawing first a red and then, without

replacement, a white marble?
5/44
31/44
5/48​

Answer 1

5/44

Explanation:

3 red, 4 blue, and 5 white = 12 marbles

P(red) = number of red / total

= 3/12 = 1/4

no replacement

2 red, 4 blue, and 5 white = 11 marbles

P(white) = number of white / total

= 5/11

P(red, no replacement, whit) = 1/4*5/11 = 5/44
