The probability that Serena does not serve an ace or a double fault is 0.6, when the probability of Serena serving an ace in tennis is 0.15, and the probability that she double faults is 0.25.
<h3>Define probability.</h3>
The formula of the favorable outcome over the total outcomes is used to describe probability. The likelihood of flipping a coin heads is one example. Given that there is only one head and two total sides, 50% of the time, a head will land up-side-down.
Given,
Serve tennis probability = 0.15
No ace probability = 1-0.15
No ace probability = 0.85
Double fault probability = 0.25
No double fault probability = 1-0.25 = 0.75
No double fault probability = 0.75
The probability of not receiving an Ace or Double Fault: is
= 0.75 ×0.85
= 0.6.
The probability that Serena does not serve an ace or a double fault is 0.6.
