Question

If the probability of having twins is 1.1%, what is the probability of not having twins?

A. 0.011

B. 0.089

C. 0.989

D. 0.999

Answer 1

The probability of not having twins can be calculated by subtracting the probability of having twins from 1. The probability of not having twins is 0.989.

Step-by-step explanation:

The probability of not having twins can be calculated by subtracting the probability of having twins from 1.

Probability of not having twins = 1 - Probability of having twins

Probability of not having twins = 1 - 0.011 = 0.989

Therefore, the probability of not having twins is 0.989.
