A bag contains marbles of 2 colors - green and blue. The theoretical probability of choosing a green marble is 0.55. The number of green marbles is 22. Find the number of blue marbles in the bag.

Sagot :

The number of blue marbles in the bag is 18.

What is the number of blue marbles?

Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.

Probability of choosing a green marble = total number of green marbles / total number of marbles

0.55 = 22/x

x = 22 / 0.55

x = 40

Total number of blue marbles = 40 - 22 = 18
