Let A and B be events with P (A) = 0.375; P (B) = 0.5, and. Calculate
0.75
0.25
0.375
0.125
First, we need to determine the probability of A' (not A) occurring. Since P(A) + P(A') = 1, we can calculate P(A') as follows:
P(A') = 1 - P(A)
P(A') = 1 - 0.375
P(A') = 0.625
Next, we need to calculate the probability of both events A and B occurring. This can be calculated as follows:
P(A and B) = P(A) * P(B)
P(A and B) = 0.375 * 0.5
P(A and B) = 0.1875
Now, we need to calculate the probability of either event A or event B occurring. This can be calculated as follows:
P(A or B) = P(A) + P(B) - P(A and B)
P(A or B) = 0.375 + 0.5 - 0.1875
P(A or B) = 0.6875
Therefore, the probability of either event A or event B occurring is 0.6875.
