Answer:
0.8 = 80% probability that he makes no more than one of the shots
Step-by-step explanation:
We have these following probabilities:
55% probability that he misses both shots.
25% that he makes one of the shots
20% probability that he makes both shots.
What is the probability that he makes no more than one of the shots?
Sum of the probabilities of missing both or making one. So
55+25 = 80%
0.8 = 80% probability that he makes no more than one of the shots
