Question

there is a 0.0503 probability that a best of seven contest that will last four games, a 0.1027 probability that will last five games a 0.2499 probability that it will last six games and a 0.5971 probability that it will last seven games. verify that this is a probability distribution. find its mean and standard deviation.

Answer 1

notice that if you add up the decimals they equal to 1

Answer 2

Let X = # of games will last in a best of 7 games contest
X is a random variable.

Answer 3

What is the mean of the probability distribution

Answer 4

The mean is \[\mu = \sum_{x}^{n} x\times f(x)\]
Where x is the number of games and f(x) is the probability that it will last x number of games.

Answer 5

i still dont understand ifi add the games is one?

Answer 6
