Math Problem Statement
Liam has a bag that contains pineapple chews, cherry chews, and lime chews. He performs an experiment. Liam randomly removes a chew from the bag, records the result, and returns the chew to the bag. Liam performs the experiment 62 times. The results are shown below: A pineapple chew was selected 58 times. A cherry chew was selected 2 times. A lime chew was selected 2 times.
Based on these results, express the probability that the next chew Liam removes from the bag will be cherry chew as a decimal to the nearest hundredth.
Solution
To find the probability that the next chew Liam removes from the bag will be a cherry chew, we need to calculate the probability based on the results of his experiment.
Liam performed the experiment 62 times, and he selected:
- 58 pineapple chews,
- 2 cherry chews,
- 2 lime chews.
The probability of an event is calculated as the ratio of favorable outcomes to total outcomes. In this case, the favorable outcome is selecting a cherry chew.
So, the probability of selecting a cherry chew is:
Now, calculating this:
Rounding to the nearest hundredth:
Thus, the probability that the next chew will be a cherry chew is 0.03.
Would you like more details or have any questions? Here are some related questions:
- How would the probability change if the number of pineapple chews was 50 instead of 58?
- How can we determine if the results are biased toward pineapple chews?
- What is the formula for calculating the probability of independent events?
- How could the probabilities be affected if Liam doesn't replace the chews after drawing?
- How do you calculate the expected value for the number of times each chew type is selected?
Tip: Probabilities are always between 0 and 1. If the experiment is fair, each outcome should have a roughly equal chance over many trials.
