Answer

Answer:

C. 7.5%

Explanation:

Step1: Identify relevant probabilities

Let $P(\text{work in morning}) = 50%=0.5$ and $P(\text{overheat later}|\text{work in morning}) = 15% = 0.15$.

Step2: Use multiplication - rule for conditional probability

The probability that the machine works in the morning and overheats later is $P(\text{work in morning and overheat later})=P(\text{work in morning})\times P(\text{overheat later}|\text{work in morning})$. Substitute the values: $0.5\times0.15 = 0.075$. Convert to percentage: $0.075\times100%=7.5%$.
