Answer:
122.5 cm²
Step-by-step explanation:
Area = 1/2 × 35 × 7 = 122.5 cm²
P(Al hits bottle first time) = 1/3
P(Al misses the first shot but hits on his second shot) =
P( Al misses and bill misses and Al hits) = 2/3 * 3/4 * 1/3 = 1/6
So required probability = 1/3 + 1/6 = 1/2
The third one is the answer?
