Question

Lydia has a bag that contains orange chews, cherry chews, and peach chews. She performs an experiment. Lydia randomly removes a chew from the bag, records the result, and returns the chew to the bag. Lydia performs the experiment 62 times. The results are shown below:

A orange chew was selected 25 times.
A cherry chew was selected 24 times.
A peach chew was selected 13 times.

Based on these results, express the probability that the next chew Lydia removes from the bag will be orange or peach as a percent to the nearest whole number.

Answer 1

The probability of selecting an orange chew is 25/62, and the probability of selecting a peach chew is 13/62. To find the probability that the next chew Lydia removes from the bag will be orange or peach, we add these probabilities:

P(orange or peach) = P(orange) + P(peach) = 25/62 + 13/62 = 38/62

To express this probability as a percent, we divide the numerator by the denominator, then multiply by 100:

P(orange or peach) = 38/62 = 0.6129...

0.6129... × 100 ≈ 61

Therefore, the probability that the next chew Lydia removes from the bag will be orange or peach, expressed as a percent to the nearest whole number, is 61%
