Final answer:
The probability of a baseball player getting a hit in 5 at-bats in a row is approximately 0.0243%.
Step-by-step explanation:
The probability of a baseball player getting a hit in an at-bat is 3/10. To find the probability of getting a hit in 5 at-bats in a row, we need to calculate the probability of getting a hit in each at-bat and multiply them together. So, the probability of getting a hit in 5 at-bats in a row is (3/10) * (3/10) * (3/10) * (3/10) * (3/10) = (3/10)^5 = 0.000243 or approximately 0.0243%
