The Deep Dive
To find the probabilities, first, we need to determine the total number of balls in the jar. There are 8 red balls, 5 white balls, and 7 yellow balls, so the total number of balls is:
Total = 8 + 5 + 7 = 20 balls.
Now let’s break down the events:
(a) The probability of drawing a red ball:
(b) The probability of drawing a ball that is NOT red:
First find the number of non-red balls:
Total non-red balls = White + Yellow = 5 + 7 = 12.
First find the number of non-red balls:
Total non-red balls = White + Yellow = 5 + 7 = 12.
© The probability of drawing a green ball:
Since there are no green balls in the jar, the probability is:
Since there are no green balls in the jar, the probability is:
