At an archery tournament, eight of the twenty competitors were left-handed and the remainders were right-handed. Due to the weather conditions it is more difficult for left-handers to hit the target. Practice sessions indicated that the probability of a left-hander hitting the target was 0.7, while for right-hander it was 0.9. What is the probability that an archer chosen at random is left-handed and hits the target?

P(left-handed AND hits target) = P(left-handed) x P(hits target)
= 8/20 x 0.7
= 8/20 x 7/10
= 56/200
= 7/25

There are 8 Left handed and 12 Right handed archers.
P(Left Handed) = 8/20 = 2/5 = 0.4
P(Hitting the target and LH) = 0.4 * 0.7 = 0.28 = 28/100 = 7/25
Option E

P(Left Handed) = 8/20 = 2/5 = 0.4
P(Hitting the target and LH) = 0.4 * 0.7 = 0.28 = 28/100 = 7/25
