Gavin has a box of crayons. There are 4 purple crayons, 3 black crayons, 3 blue crayons, and 2 red crayons. What is the probability Gavin will draw a purple crayon, put it on the table, and then draw another purple?

The chances that he does this are 4 in 144, or 1 in 36.

Step-by-step explanation:

The chances he chooses a purple are 4 in 12. 4 in 12 times 1 in 12 is 4 in 144, which can be simplified to 1 in 36.

180

step-by-step explanation:

12-2=10

20-2=18

18x10=180

you ignore the remainder, therefore the answer is y = x+2

step-by-step explanation:

you have to divide the denominator by the numerator. you can use synthetic division or long division.

[-5] .     1 .     7 .     11

x + 2 + 1/x+5
