Answer 2

"At least one" = either 1, 2 or 3.

If the events are independent, the probability of both/all events occurring is determined by multiplying the probabilities of the individual events.

for 1: .0479 * (1-.0479)^2 = ?

for 2: .0479^2 * (1-.0479) = ?

for 3: .0479^3 = ?

Either-or probabilities are found by adding the individual probabilities.
