Given:

3 White marbles

7 blue marbles

Determine the probability of picking a blue marble.

Solution:

Since there are 23 white marbles and 7 blue marbles, the total number of marbles is 10. In order to determine what is the probability of picking blue marbles in a bag, we simply put the total number of blue numbers over the total number of marbles.

Probability  = 7/10

The answer is 7/10 , or 70%.
