Question

You have a batting average of .250. This means that the probability of your getting a hit is 25%. If you have 520 attempts this season, how many hits can you expect to get?

Answer 1

To calculate how many hits you can expect to get with a batting average of .250 and 520 attempts, you can multiply the number of attempts by the probability of getting a hit:

Expected hits = 520 attempts x 0.25 (25% batting average)
Expected hits = 130

Therefore, you can expect to get 130 hits in a season with 520 attempts and a batting average of .250.

Answer 2

A greenhouse manager knows, from experience, that the probability of a plant surviving the winter is 3/5. If her greenhouse has 270 plants, how many plants can she expect to survive the winter?

Answer 3

To calculate how many plants the greenhouse manager can expect to survive the winter with a probability of 3/5, you can multiply the total number of plants by the probability of survival:

Expected surviving plants = 270 plants x 3/5 (probability of survival)
Expected surviving plants = 162

Therefore, the greenhouse manager can expect 162 plants to survive the winter out of the 270 plants in the greenhouse.

Answer 4

Judging from past basketball games, the probability that you make a free throw is 4/5. If you get 220 attempts this season, how many free throws can you expect to make?

Answer 5

To calculate how many free throws you can expect to make with a probability of 4/5 and 220 attempts, you can multiply the number of attempts by the probability of making a free throw:

Expected made free throws = 220 attempts x 4/5 (probability of making a free throw)
Expected made free throws = 176

Therefore, you can expect to make 176 free throws in a season with 220 attempts and a free throw probability of 4/5.
