If A, B, C are events such that P(A) = 0.3,P(B) = 0.4, P(C) = 0.8, P(A∩B) = 0.08, P(A∩C) = 0.28 P(A∩B∩C) = 0.09 If P(A ∪ B ∪ C) ≥ 0.75, then find the range of x = P(B∩C) lies in the interval
A machine has three parts, and
, whose chances of being defective are
and
respectively. The machine stops working if any one of the parts becomes defective. What is the probability that the machine will not stop working?
The probability that at least one of the events A and B occurs is 0.6. If A and B occur simultaneously with probability 0.2, then the value of is: (where
are complements of
and
respectively)
An aircraft has three engines and
. The aircraft crashes if all the three engines fail. The probabilities of failure are
and
for engines
and
respectively. What is the probability that the aircraft will not crash?
Let A and B be two events. Then 1+P(A∩B)−P(B)−P(A) is equal to
Given two mutually exclusive events A and B such that P(A) = 0.45 and P(B) = 0.35, P(A∩B) is equal to
If and
are independent events of a random experiment such that
