The probability of events A, B, and C happening simultaneously is 1/24.
Since events A, B, and C are independent, the probability of their intersection is the product of their individual probabilities. Therefore:
P(An Bn C) = P(A) * P(B) * P(C)
Substitute the given values:
P(An Bn C) = 1/3 * 1/4 * 1/2 = 1/24
Therefore, the probability of events A, B, and C happening simultaneously is 1/24.
