Question

A jar contains 7 blue marbles, 11 red marbles, and 19 green marbles. You pick one marble from the jar. Find the theoretical probability, P(red). Write your answers as a decimal rounded to nearest hundredth place.

Answer 1

Explanation:

blue marbles = 7

red marbles = 11

and green marbles = 19

Total marbles = 11+19+7 = 37

Prob(red) = 11/37 = 0.297 ≈ 0.3
