Question: If the probability of rain tomorrow is 0.7, what is the probability that it will not rain?

Options:

Correct Answer: 0.3

Solution:

The probability that it will not rain is 1 - 0.7 = 0.3.

If the probability of rain tomorrow is 0.7, what is the probability that it will not rain?

If the probability of rain tomorrow is 0.7, what is the probability that it will not rain?

Step 1: Understand that the probability of an event happening and the probability of it not happening must add up to 1.
Step 2: Identify the given probability of rain tomorrow, which is 0.7.
Step 3: Use the formula to find the probability of it not raining: Probability of not raining = 1 - Probability of raining.
Step 4: Substitute the given probability into the formula: 1 - 0.7.
Step 5: Calculate the result: 1 - 0.7 = 0.3.
Step 6: Conclude that the probability that it will not rain is 0.3.

Probability Complement – Understanding that the probability of an event not occurring is equal to 1 minus the probability of the event occurring.
