A collegiate video-game competition team has a 0.65 probability of winning a match. Over the course of a season, 12 matches are played. Individual matches are independent of any other matches. Calculate the probability that the team will win exactly 6 matches over the course of one season. [ENTER ANSWER TO 4 DECIMAL PLACES, e.g. a 75% probability would be entered as "0.7500"]
Given:
A collegiate video-game competition team has a 0.65 probability of winning a match. Over the course of a season, 12 matches are played.
Probability of winning match, p= 0.65
Number of trials, n= 12
Let X : The team will win matches over the course of one season.
X follows the Binomial Distribution.
X ~ Binomial(n=12, p = 0.65)
The probability function of Binomial Distribution is given by
P(X=x) = nCx * p^x * (1-p)^n-x
The probability that the team will win exactly 6 matches over the course of one season :
P(X=6) = 12C6 * (0.65)^6 * (1-0.65)^12-6
= 0.1281
Therefore the probability that the team will win exactly 6 matches over the course of one season is 0.1281
