Zachary has a bag that contains strawberry chews, cherry chews, and peach chews. He performs an experiment. Zachary randomly removes a chew from the bag, records the result, and returns the chew to the bag. Zachary performs the experiment 66 times. The results are shown below:A strawberry chew was selected 61 times.A cherry chew was selected 3 times.A peach chew was selected 2 times.If the experiment is repeated 200 more times, about how many times would you expect Zachary to remove a peach chew from the bag? Round your answer to the nearest whole number.Answer:
Q. Zachary has a bag that contains strawberry chews, cherry chews, and peach chews. He performs an experiment. Zachary randomly removes a chew from the bag, records the result, and returns the chew to the bag. Zachary performs the experiment 66 times. The results are shown below:A strawberry chew was selected 61 times.A cherry chew was selected 3 times.A peach chew was selected 2 times.If the experiment is repeated 200 more times, about how many times would you expect Zachary to remove a peach chew from the bag? Round your answer to the nearest whole number.Answer:
Determine total number of experiments: Determine the total number of experiments conducted initially. Zachary performed the experiment 66 times.
Determine peach chew selections: Determine the number of times a peach chew was selected. A peach chew was selected 2 times out of the 66 experiments.
Calculate experimental probability: Calculate the experimental probability of selecting a peach chew. Experimental probability of selecting a peach chew =Total number of experimentsNumber of times a peach chew was selected=662
Simplify the probability: Simplify the probability.Experimental probability of selecting a peach chew = 662= 331
Predict outcome of additional experiments: Use the experimental probability to predict the outcome of 200 additional experiments.Expected number of times a peach chew will be selected = Probability of selecting a peach chew × Number of additional experiments=(331)×200
Perform calculation for expected selections: Perform the calculation to find the expected number of times a peach chew will be selected.Expected number of times a peach chew will be selected ≈(1/33)×200≈6.0606
Round expected selections: Round the result to the nearest whole number.Expected number of times a peach chew will be selected ≈6 (rounded to the nearest whole number)
