Pablo plays 3 rounds of a game, in which his chances of winning each round are 1/5, 1/3, and 1/n, respectively. If n ≠ 0, what is the probability that Pablo wins the first two rounds, but loses the third?
Answer/Solution
(n-1)/15n
Steps/Work
1/5 * 1/3 * (1-1/n)
= 1/15 * (n-1)/n
= (n-1)/15n
Answer - B
= 1/15 * (n-1)/n
= (n-1)/15n
Answer - B
