The probability of winning a lottery ticket is 0.1. Find the probability that at least one of the four purchased tickets is winning.
The probability that the ticket is winning: p = 0.1;
The probability that the ticket is not winning: q = 1 – p = 1 – 0.1 = 0.9;
The probability that none of the tickets are winning:
P = q ^ 4 = 0.9 ^ 4 = 0.6561.
The probability of an opposite event such that at least one ticket is winning:
P` = 1 – P = 1 – 0.6561 = 0.3439.
Answer: 0.3439.
