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.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

answer: 3.26019516
