Question

there were 3 apple 1 mixed fruit 2 grape and 4 tropical fruit juice boxes in the cooler at the picnic what is the probability that when jill reaches into the cooler to grab 2 juice boxes without replacing them she grabs 2 that are grape?

Answer 1

Total juice boxes = 3 + 1 + 2 + 4 = 10

probability first one out is grape = 2 / 10
probablility second one out is grape 1 / 9 (one taken already and only nine left)

total probability = 2 / 10 x  1 / 9 = 2 / 90 = 1 / 45

Answer 2

The probability that when jill reaches into the cooler to grab 2 juice boxes without replacing them she grabs 2 that are grape is 1/ 45.

What is the probability?

Probability refers to a possibility that deals with the occurrence of random events.

The probability of all the events occurring need to be 1.

P(E) = Number of favorable outcomes / total number of outcomes

There were 3 apples 1 mixed fruit 2 grapes and 4 tropical fruit juice boxes in the cooler at the picnic.

Total juice boxes = 3 + 1 + 2 + 4

                             = 10

The probability of the first one out is grape = 2 / 10

The probability second one out is grape = 1 / 9

The total probability = 2 / 10 x  1 / 9

                                  = 2 / 90

                                  = 1 / 45
