Add -1(row 2) to row 3:
Multiply through row 3 by 1/9:
Add 5(row 3) to row 2:
Multiply through row 2 by -1/3:
Add -2(row 2) and -1(row 3) to row 1:
So we have .

Answer:
14) b) P(B/A) = 0.50
15) P(A or B) = 0.7
Step-by-step explanation:
14)
Given P(A) = 0.4 and P(B) = 0.5 and P(A and B) = 0.2
Conditional probability of B given that A
15)
By using Addition theorem on probability
P( A ∪ B) = P(A) + P(B) - P(A∩B)
= 0.4 +0.5 - 0.2
P( A ∪ B) =0.7
