Question

A bag contains 5 red marbles, 10 blue marbles, and 14 yellow marbles. If Jen selects a marble from the bag without looking, what is the probability that she will not pull a red marble

Answer 1

The answer to your question is 0.83 or 83%

Explanation:

Data

5 red marbles

10 blue marbles

14 yellow marbles

Process

1.- Calculate the total amount of marbles

Total amount = 5 red + 10 blue + 14 yellow

Total amount = 29 marbles

2.- Calculate the amount of marbles that are not red

No red marbles = 10 + 14

= 24 marbles

3.- Calculate the probability

Probability of not pulling a red marble =
`(no red marble)/(total amount of marbles)`

Probability of not pulling a red marble =
`(24)/(29) = 0.83 or 83%`
