Persons

Persons surveyed:100 with the result:

Volleyball = 15%
Baseball = 9%
Sepak Takraw = 8%
Pingpong = 8%
Basketball = 60%

Find the average of how many like Basketball and Volleyball. Would you please show your solution?

Correct answer:

p =  75 %

Step-by-step explanation:

$$\begin{gathered} n=100 \\ {n}_1=\frac{60}{100}\cdot n=\frac{60}{100}\cdot 100=\frac{60\cdot 100}{100}=\frac{6000}{100}=60 \\ {n}_2=\frac{15}{100}\cdot n=\frac{15}{100}\cdot 100=\frac{15\cdot 100}{100}=\frac{1500}{100}=15 \\ p=100\cdot \frac{n_1+n_2}{n}=100\cdot \frac{60+15}{100}=75\% \end{gathered}$$
