What is Probability?

Probability is the likelihood or chance that an event will occur

Conditional probability

Given the following parameters from thee given information:

p[a] = 0.20

p[not b] = 0.40

p[b|a] = 0.25

Based on the formula for calculating the conditional probability:

P(A/B) = P(A∩B)/P(B)

P(B/A) = p(B or A)/P(A)

p(A or B) = P(B/A)p(B)

p(A or B) = 0.25 (0.6)

p(A or B) = 0.15

Hence the value of p(A or B) is 0.15
