If A,B and C are three independent events such that
P(A)=P(B)=P(C )=p,
then P (atleast two of A,B and C occur)=`3p^(2)-2p^(3)`

To solve the problem of finding the probability that at least two of the independent events A, B, and C occur, we will follow these steps: ### Step 1: Understand the Events We have three independent events A, B, and C, each with a probability of occurrence \( P(A) = P(B) = P(C) = p \). ### Step 2: Calculate the Total Probability The total probability of all possible outcomes for three independent events can be calculated using the principle of inclusion-exclusion. We need to find the probabilities of the following cases: 1. Exactly two events occur. ...
