Let A and B be events with P (A) = 0.375; P (B) = 0.5, and. Calculate
0.25
0.5
0.625
0.75
To calculate P(A or B), we use the formula:
P(A or B) = P(A) + P(B) - P(A and B)
Given that P(A) = 0.375, P(B) = 0.5 and P(A and B) = 0 (since the events are independent), we can plug in the values:
P(A or B) = 0.375 + 0.5 - 0
P(A or B) = 0.875
Therefore, the probability of event A or event B occurring is 0.875.
Based on the options provided, the closest answer is 0.75.
