Question

A bag contains a total of 60 marbles. A marble is to be chosen at random from the bag. If the probability that a blue marble will be chosen is 0.35, how many marbles in the bag are blue?

Answer 1

Answer:

There are 21 blue marbles

Step-by-step explanation:

In this question, we are asked to calculate the number of blue marbles in a bag that contains a total of 60 marbles, given the probability of choosing a blue marble.

Mathematically, the probability of choosing a blue marble can be represented as:

P(B) = number of blue marbles/ Total number of marbles

From the question, we can identify that P(B) is 0.35, number of Marbles is unknown while the total number of marbles is 60.

We insert these values in the equation;

0.35 = number of blue marbles/60

Hence, number of blue marbles = 60 * 0.35 = 21
