In a family of 3 children, the probability of having at least one boy is:

1. $\Big(\dfrac{1}{8}\Big)$

2. $\Big(\dfrac{5}{8}\Big)$

3. $\Big(\dfrac{3}{4}\Big)$

4. $\Big(\dfrac{7}{8}\Big)$

A number is chosen randomly from 10 to 99 (both inclusive) such that each number is equally likely to be chosen. The probability that at least one digit of the chosen number is 8 is:

1. $\Big(\dfrac{1}{5}\Big)$

2. $\Big(\dfrac{1}{9}\Big)$

3. $\Big(\dfrac{1}{10}\Big)$

4. $\Big(\dfrac{19}{20}\Big)$

One card is drawn at random from a pack of 52 playing cards. What is the probability that the card drawn is a face card?

1. $\Big(\dfrac{1}{13}\Big)$

2. $\Big(\dfrac{3}{13}\Big)$

3. $\Big(\dfrac{1}{4}\Big)$

4. $\Big(\dfrac{9}{52}\Big)$

A card is drawn from a pack of 52 playing cards. The probability of getting a queen of club or a king of heart is:

1. $\Big(\dfrac{1}{13}\Big)$

2. $\Big(\dfrac{2}{13}\Big)$

3. $\Big(\dfrac{1}{26}\Big)$

4. $\Big(\dfrac{1}{52}\Big)$
