Question

The probability of Keith winning a chess game against Sam is 0.4. What is the probability that Keith will not win 3 games in a row?

Answer 1

What is the probability of him losing 1 game?

Answer 2

Are you asking me? cuz I have no idea.... I hate Probability

Answer 3

But I guess it has to add up to 1 so 1-0.4=0.6 right...??

Answer 4

good, the probability of him losing any given game is 0.6

so the probability of losing 3 in a row is 0.6*0.6*0.6 = 0.216

shortcut: 0.6^3 = 0.216

Answer 5
