Q
Q: If the probability of an event A is 0.7, what is the probability of the event not occurring?
Solution:
Probability of not A = 1 - P(A) = 1 - 0.7 = 0.3.
Steps: 7
Show Steps
Step 1: Understand that the probability of an event A occurring is given as 0.7.
Step 2: Know that the total probability of all possible outcomes is always 1.
Step 3: To find the probability of event A not occurring, we subtract the probability of A from 1.
Step 4: Use the formula: Probability of not A = 1 - P(A).
Step 5: Substitute the value of P(A) into the formula: Probability of not A = 1 - 0.7.
Step 6: Calculate the result: 1 - 0.7 = 0.3.
Step 7: Conclude that the probability of event A not occurring is 0.3.
