The conditional probabilities are calculated as:
1) P(A or B) = 100%
2) p(A and B) = 0.2331
3) P(A | B) = 0.63
4) P(not B | not A) = 0
How to find the conditional probability?
1) p(A or B) = p(A) + p(B).
We have:
p(A) = 63/100 = 0.63
P(B) = 37/100 = 0.37
Thus:
P(A or B) = 0.63 + 0.37 = 100%
2) p(A and B) = p(A) * p(B)
p(A and B) = 0.63 * 0.37
p(A and B) = 0.2331
3) P(A | B) = P(A ∩ B)/P(B)
P(A | B) = 0.2331/0.37
P(A | B) = 0.63
4) P(not B | not A) = 0
