Ten tiles numbered 1 through 10 are placed in a bag. You randomly choose one tile. Without replacing the first tile, you randomly choose a second tile. Find the probability of choosing the 4 and then a number less than 5. Write your answer as a fraction in simplest form.

The probability is ?

Hello there!

We have 10 tiles, meaning there is 1 of every tile from 1 to 10.

So, 4 is 1/10 and any number less than 5 is 3/9 after we pick the 4.

Multiply them to get our probability.

1/10 x 3/9 = 3/90

Simplify: 3/90 = 1/30

Therefore, the probability of picking the 4 and then a number less than 5 without the 4 is 1/30.
