Question

Tony has a jar that contains 16 red, 8 blue, 7 black, and 1 yellow marble. What is the theoretical probability of selecting a blue marble?

Answer 1

`(1)/(4)`

Explanation:

Number of blue marbles = 8

Total number of marbles = 16+8+7+1=32

`probability\: of \:selecting\: a\: blue\; marble\\=(Number\: of\:blue\: marbles)/(Total\: number\: of\: marbles) \\\\=(8)/(32) \\\\=(1)/(4)`
