Question

In a certain family, the probability of having twins in 0.08 and the probability of having a single baby is 0.92. What is the probability of a family having two sets of twins?

Answer 1

0.0064

Explanation:

Probability (2 sets of twins) :

• When a probability of an event is asked multiple, apply the number of times as an exponent to the probability of the event
• P = (0.08)²
• P = (8 x 10⁻²)²
• P = 64 x 10⁻⁴
• P = 0.0064
