Question

Jennifer has 7 marbles in her bag. She has 4 blue, 1 white, 1 pink, and 1 yellow. She chooses one marble without looking. What is the probability that Jennifer picks one blue marble?

Answer 1

`(4)/(7)`

Explanation:

Jennifer has 7 marbles in her bag consisting of 4 blue, 1 white, 1 pink, and 1 yellow.

The probability of her picking a blue marble is gotten by dividing the number of blue marbles that she has by the total number of marbles.

Therefore, the probability of picking a blue marble is:

`(4)/(7)`
