→ The probability of the five of them being rejected will be = (0.92)⁵ = {(0.92)*(0.92)*(0.92)*(0.92)*(0.92)} ≈ 0.659. (Ans.)
What is the probability of getting 1 and 5 If a dice is thrown once?
So they are mutually exclusive events, therefore their probabilities add to 1. By symmetry we expect that each face is equally likely to appear and so each has probability = 1/6. The outcome of a 5 is one of those events and so has probability = 1/6 of appearing.
