Solution: If A B0 and C0 were independent we could apply the product formula and the answer would be immediate but we don’t know this (in fact they are not) However from a Venn diagram we see that P(A?B0?C0) is equal to to P(A)?P(A? B)?P(A?C)+P(A?B?C) Inserting the given values we get 0 6?0 3?0 4+0 2 = 0 1 as

What is the value of P (A?B) if there are two independent events?

If Aand Bare two independent events, then write P(A? B) in terms of P(A) and P(B). Answer: A and B are two independent events.? PA?B¯=PAPB¯=PA1-PB=PA-PAPB Page No 31.103: Question 15: If P(A) = 0.3, P(B) = 0.6, P(B/A) = 0.5, find P(A? B). Answer:

How to find P(A/B) if A and B are two events?

If Aand B are two events such that P(A? B) = 0.32 and P(B) = 0.5, find P(A/B). Answer: Given:PB=0.5 PA?B=0.32Now,PAB=PA?BPB? PAB=0.320.5=3250=0.64 Page No 31.34: Question 4: If P(A) = 0.4, P(B) = 0.8, P(B/A) = 0.6.

How do you prove that A and B are independent events?

If Aand Bbe two events such that P(A) = 1/4, P(B) = 1/3 and P(A? B) = 1/2, show that Aand Bare independent events. Answer: PA?B =PA+ PB-PA?B?PA?B =PA+ PB-PA?B?PA?B =14+13-12?PA?B =3+4-612?PA?B =112=14×13=PAPBThus, A and B are independent events.

What is P(A and B) in probability?

Let A and B be two independent events such that P (A) = 0.4 and P (B) = 0.4. What is P (A and B)? This is a joint probability. To handle these, you multiply the probabilities of all the independent events. What’s a good investment for 2022? This might sound unconventional, but hands down I’d go with blue-chip art.
