Question #10

10. An ice chest contains 9 can of apples juice, 8 cans of grape juice, 7 cans of orane juic, and 5 cans of pineapple juice. Suppose you reach into the container and randomly select a can. What is the probability that you will pull a...

- apple juice
- grape juice
- pineapple or orange juice

The top is the part and the bottom is the total. The number cans of apple juice is 9, and the total number of cans is 29. Scince we're finding the percent, we divide 9 by 29, which gives us 0.3103... then we multiply 0.3103 by 100, (because percents are always out of 100) which gives us 31.03%. The probability of getting a can of apple juice is 31.03%

This is pretty much the same as the first one, except the numbers are different.
8 divided by 29 equals 0.27.58. 0.27.58 multiplied by 100 equals 27.58%.
The probability of getting a can of grape juice is 27.58%.

(Pineapple and Orange Juice) .. This one is a little bit different. The questions asks for the probability of pineapple OR orange juice. So you combine both. 7 cans of orange juice plus 5 cans of pineapple juice equals 12 cans. 12 divided by 29 equals 0.4137. That, multiplied by 100 is 41.37%. The probability of pulling out a can of pineapple juice or a can of orange juice is 41.37%.
