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

Answer:

$\frac{1}{4}$

Step-by-step explanation:

Number of blue marbles = 8

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

$probability\: of \:selecting\: a\: blue\; marble\\=\frac{Number\: of\:blue\: marbles}{Total\: number\: of\: marbles} \\\\=\frac{8}{32} \\\\=\frac{1}{4}$
