The odds of winning a game at a carnival are 3 in 7. If Angie plays the game nine times, what is the probability that she wins exactly two times

Respuesta :

Answer:

13%

Step-by-step explanation:

C(n, x) • [tex]p^{x}[/tex] • [tex]q^{n-x}[/tex]

x = number of successes = 2

p = probability of success = 3/7

q = probability of failure = 1 = 3/7

n = number of games

(3/7)^2 x (4/7)^(9-2) = 13%
