The table below shows a baseball player’s batting average batting left and right versus left- and right-handed pitches Left-handed pitchers Right-handed pitchers Bats left 0.285 0.175 Bats right 0.215 0.250 Assume these numbers are the probabilities that he will get a hit during an “at bat.” On average, when he bats left 100 times, how many more hits will he get when he faces left-handed pitchers as opposed to right-handed pitchers? 1 2 11 22

Question
Answer:
Answer:C. 11 is the correct answerStep-by-step explanation:The table representing the probabilities of player's batting average is,                         Left-Handed pitchers         Right-Handed pitchersBats Left                    0.285                                      0.175Bats Right                   0.215                                      0.250So, when the players bats left 100 times,The probability of hits he gets when faced by left-handed pitchers = 0.285 × 100 = 28.5The probability of hits he gets when faced by right-handed pitchers = 0.175 × 100 = 17.5Thus, the difference in the hits = 28.5 - 17.5 = 11Hence, the player will get 11 more hits t when he faces left-handed pitchers as opposed to right-handed pitchers.
