Question

The TV weather forecaster announces that one location has a 30% chance of rain tomorrow and a 35% chance of hail. What is the probability that it will rain or hail in this location?

Answer 1

Answer: 65%

Step-by-step explanation:

When in probability and the outcome is mutually exclusive which means that either one or the other will happen then the probabilities of the events should be added up.

P(A or B) = P(A) + P(B)

P(Rain or Hail) = P(Rain) + P(Hail)

P(Rain or Hail) = 30% + 35%

P(Rain or Hail) = 65%
