Question

A glass jar contains 3 red, 13 green, 4 blue, and 8 yellow marbles. If a single marble is chosen at random from the jar, what is the probability of choosing a(a) red marble? (b) green marble? (c) blue marble?

Answer 1

(a) red marble?

`p=\frac{\text{red}}{\text{total}}=(3)/(3+13+4+8)=(3)/(28)`

(b) green marble?

`p=\frac{\text{gren}}{\text{total}}=(13)/(3+13+4+8)=(13)/(28)`

(c) blue marble?​

`p=\frac{\text{blue}}{\text{total}}=(4)/(3+13+4+8)=(4)/(28)`
