A number from 22 to 29 is drawn out of a bag at random. What is the theoretical probability of NOT drawing 28?

Probability = 5/6

Step-by-step explanation:

Between 22 and 29, 28 can only come once. There are a total of 6 numbers between 22 and 29 (23, 24, 25, 26, 27, 28).

Step 1: Write the formula of probability

Probability = number of possible outcomes/total number of outcomes

There is only one 28 so the chance of getting a 28 is 1/6.

Not getting a 28 would mean getting any one number from 23, 24, 25, 26 and 27.

Step 2: Apply the probability formula

Probability = number of possible outcomes/total number of outcomes

Probability of not getting 28 = 5/6
