Answer

Explanation:

Step1: Identify the events

We have two mutually - exclusive events: hitting a single and hitting a double.

Step2: Apply the addition rule for mutually - exclusive events

For mutually - exclusive events (A) and (B), (P(A\cup B)=P(A)+P(B)). Let (A) be the event of hitting a single and (B) be the event of hitting a double. Given (P(A) = 0.15) and (P(B)=0.05). So (P(A\cup B)=0.15 + 0.05).

Step3: Calculate the result

(P(A\cup B)=0.20) or 20 percent.

Answer:

20 percent
