Answer

Explanation:

Step1: Calculate loss - percentage

The sum of win - percentage, draw - percentage and loss - percentage is 100%. Given win percentage = 65% and draw percentage = 15%. So loss percentage $=100-(65 + 15)=20%$.

Step2: Calculate number of losses

The team plays 20 matches. The number of matches expected to be lost is 20% of 20. Using the formula $n = p\times N$, where $p$ is the proportion (0.2 in decimal form for 20%) and $N$ is the total number of matches (20). So $n=0.2\times20 = 4$.
