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

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.

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.

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.
