Calculate P (A or B) in the following scenarios: c. P(A)=0.69, P(B) = 0.68, P(A and B)=0.58 P (A or B)=
To calculate the probability of A or B occurring, we can use the formula:
P(A or B) = P(A) + P(B) - P(A and B)
Given that P(A) = 0.69, P(B) = 0.68, and P(A and B) = 0.58, we can substitute these values into the formula:
P(A or B) = 0.69 + 0.68 - 0.58
= 1.37 - 0.58
= 0.79
Therefore, P(A or B) = 0.79.
