If the chance of a single lottery ticket being a winner is 0.2, what is the probability of winning at least once when buying 4 tickets?

Explanation

To find the probability of winning on at least one ticket, calculate 1 minus the probability of losing on all four tickets. Since the chance of losing a single ticket is 0.8, the probability of losing all four is (0.8)^4 = 0.4096. Therefore, the probability of winning at least once is 1 - 0.4096 = 0.5904.
