Question

select the correct answer. a soccer team wins 65% of its matches, and 15% of its matches end in a draw. if the team is scheduled to play 20 matches, about how many matches is it expected to lose? a. 13 b. 4 c. 8 d. 1

Explanation:

Step1: Calculate the percentage of losses

The sum of win - percentage and draw - percentage is $65\%+15\% = 80\%$. The percentage of losses is $100\%-(65\% + 15\%)=20\%$.

Step2: Calculate the number of expected losses

If the team plays $n = 20$ matches, and the probability of losing a match is $p=0.2$, the expected number of losses is $n\times p$. So, $20\times0.2 = 4$.

Answer:

B. 4
