Question

The probability of raining in a city on a particular day is 0.24. What is the probability that there won't be any rainfall in the city on that day?

• A. 0.76
• B. 0.26
• C. 1
• D. 0.06

Answer 1

The correct option is A 0.76

The given experiment can have two possible outcomes.
1. Raining in city (R)
2. Not raining in city (not R)

In terms of probabilities of raining in city or not raining in city:
1. P(R)
2. P(not R)

Sum of probabilities of all possible outcomes = 1

∴ P(R) + P(not R) = 1

Given , P(R) = 0.24

So, P(not R) = 1 - P(R)

= 1 - 0.24

= 0.76

Hence, the probability of not raining in the city is 0.76
