Question

that the child has age $8$ and has less than $50$ toys.

• A. $\frac{7}{100}$
• B. $\frac{9}{100}$
• C. $\frac{9}{50}$
• D. $\frac{11}{60}$

Answer 1

The correct option is B $\frac{9}{100}$

Total no. of childrens $=3+8+20+15+6+12+18+11+22+17+15+10+13+10+10+10=200$

$P\left(B\right)=\frac{\text{No. of children having age of 8 and less than 50 toys}}{\text{Total no. of childrens}}$

$=\frac{6+12}{200}=\frac{18}{200}=\frac{9}{100}$
