Compute the probability of a family, chosen at random, having

• A. 2 girls
• B. 1 girl
• C. No girl
• D. 3 girls

Answer 1

The correct option is A 2 girls

Total no .of families $1500$

No .of families with $2$ children is $475$

Probability of picking them is $\frac{475}{1500}=\frac{19}{60}$

No .of families with $1$ children is $814$

Probability of picking them is $\frac{814}{1500}=\frac{407}{750}$

No .of families with $2$ children is $211$

Probability of picking them is $\frac{211}{1500}$
