A basketball player claims to make 47%of her shots from the field. We want to simulate the player taking sets of 10shots, assuming that her claim is true.

To simulate the number of makes in 10shot attempts, you would perform the simulation as follows:

a. Use 10 random one-digit numbers, where 0-4are a make and 5-9are a miss.

b. Use 10random two-digit numbers, where 00-46are a make and 47-99are a miss.

c. Use 10random two-digit numbers, where 00-47are a make and 48-99are a miss.

d. Use 47random one-digit numbers, where 0is a make and 1-9are a miss.

e. Use 47random two-digit numbers, where 00-46are a make and 47-99are a miss.
