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%.
