Question 1
1 / -0

Let A and B be independent events with P (A) = 0.3 and P(B) = 0.4. Find P(A ∩ B)

A
0.15

B
0.14

C
0.10

D
0.12

Solution

Let A and B be independent events with P (A) = 0.3 and P(B) = 0.4
P( A ∩ B ) = P(A) . P(B)

⇒P( A ∩ B ) = 0.3 × 0.4 = 0.12
Question 2
1 / -0

Let A and B be independent events with P (A) = 0.3 and P(B) = 0.4.Find P(A ∪ B)

A
0.62

B
0.51

C
0.58

D
0.55

Solution

Let A and B be independent events with P (A) = 0.3 and P(B) = 0.4
Since the events are independent, P(A ∩ B) = P(A).P(B)

Therefore P(A ∪ B) = P(A) + P(B) = 0.3 + 0.4 - 0.12 = 0.58
Question 3
1 / -0

Let A and B be independent events with P (A) = 0.3 and P(B) = 0.4. Find P (A|B)

A
0.3

B
0.27

C
0.2

D
0.33

Solution

Let A and B be independent events with P (A) = 0.3 and P(B) = 0.4 P(A/B) = P(A) = 0.3.
Question 4
1 / -0

Let A and B be independent events with P (A) = 0.3 and P(B) = 0.4. Find P(B|A).

A
0.4

B
0.2

C
0.3

D
0.5

Solution

Let A and B be independent events with P (A) = 0.3 and P(B) = 0.4. P(B/A) = P(B) = 0.4
