Q: If the probability of an event is 0.7, what is the probability of its complement?
Solution:
Probability of complement = 1 - P(event) = 1 - 0.7 = 0.3.
Steps: 6
Show Steps
Step 1: Understand that the probability of an event is given as 0.7.
Step 2: Know that the complement of an event is what happens when the event does not occur.
Step 3: Remember the formula for finding the probability of the complement: Probability of complement = 1 - P(event).
Step 4: Substitute the given probability into the formula: Probability of complement = 1 - 0.7.
Step 5: Calculate the result: 1 - 0.7 = 0.3.
Step 6: Conclude that the probability of the complement is 0.3.
