Cami plays softball. The table to the right shows the frequency of the number of hits she has per game. a) For a randomly selected game, what is the probability that she gets exactly 2 hits? b) What is the probability that she gets at most two hits c) What is the probability that she gets at least one hit? Number of Frequency hits 14 1 18 11 3 8 4 a) How is the probability that she gets exactly 2 hits found? O A. Find the sum of the probabilities of three hits and four hits. B. Subtract the probability of two hits from 1. O C. Find the sum of the probabilities of no hits, one hit, and two hits. O D. Divide the frequency of two hits by the total. The probability that she gets exactly two hits is (Simplify your answer.)

Subtract the probability of two hits from 1. O C. Find the sum of the probabilities of no hits, one hit, and two hits. O D. Divide the frequency of two hits by the total. The probability that she gets exactly two hits is (Simplify your answer.)
b) What formula should be used to find the probability that she gets at most two hits? O A. P(at most two hits) = 1- (P(three hits) + P(four hits)) O B. P(at most two hits) = P(three hits) +P(four hits) O C. P(at most two hits) = P(no hits) + P(one hit) O D. P(at most two hits) = 1- P(two hits) The probability that she gets at most two hits is (Simplify your answer.) c) What formula should be used to find the probability that she gets at least one hit? O A. P(at least one hit) = P(two hits) + P(three hits) + P(four hits) O B. P(at least one hit) = 1- (P(no hits) + P(one hit)) O C. P(at least one hit) = P(no hits) + P(one hit) O D. P(at least one hit) = 1- P(no hits) The probability that she gets at least one hit is (Simplify your answer.)
