Question

A bowl contains 28 black,21 red,23 blue,and 10 green balls.A ball is drawn at random. P(blue)

Answer 1

To find the probability of picking a blue marble, first we add all the marbles together:
28+21+23+10=82

since there are 23 blue marbles in the bag out of a total of 82 marbles, the probability of picking a blue marble is 23/82.

P(blue)= 23/82

hope this helps

Answer 2

P(blue) is 23/82 the sum is 82 and there is 23 blue balls
