Question

You have tiles numbered 1-9 in a bag. What is the probability of drawing a multiple of 3,putting it aside, and then drawing the number 5

Answer 1

Answer:

1/18

Step-by-step explanation:

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

Multiples of 3 between 1 - 9 = 3,6,9

Probability of picking a multiple of 9 = total multiples of 9 in the bag / total tiles in the bag

3/9

To transform to the simplest form. divide both the numerator and the denominator by 3

1/3

After picking the multiples of 3, the tiles are not replaced, tiles in the bag would now be 6

Probability of picking 5 = 1/6

1/6 x 1/3 = 1/18
