Option A , C, D are true.

Step-by-step explanation:

Given : In a carnival game, there is a 45% probability of winning a prize.

To find : Which of the following is true.

Solution : Probability of winning a prize is 45%

or $\frac{45}{100}=\frac{9}{20}=0.45$

Total probability of an event is 1

Probability of winning is 0.45

Then probability of loosing is 1-0.45=0.55

or $0.55=\frac{55}{100}=\frac{11}{20}$

From the results we can say that,

A) The probability that you won't win is 11/20 is true

B) The probability that you will win is 4.5 is false

C) The probability that you won't win is 0.55 is true

D) The probability that you will win is 9/20 is true

Therefore, Option A , C, D are true and B is false.
