The probability of Elizabeth winning the soccer game is 0.72. What is the probability of not winning the game?
Rom4ik [11]

Answer:

.28 = P( not winning)

Step-by-step explanation:

The probability of winning is .72

The 2 possibilitites are winning and not winning.  They must total 1

1 = P(winning) +P( not winning)

1 = .72 + P( not winning)

Subtract .72 from each side

1-.72 = P( not winning)

.28 = P( not winning)
