8)If there are 4 yellow, 2 blue, 1 red, and 3 green marbles in a bag, what is the
probability you choose a blue marble at random, P(blue)?
What is the Pſyellow)?

P(blue)=1/5. P(yellow)=2/5.

Step-by-step explanation: First find the total number of marbles. 4+1+2+3=10. To find the probability of blue marbles, use this equation (number of blue marbles (2) / total number of marbles(10) ). 2/10=1/5.

To find the probability of yellow marbles do this equation (number of yellow marbles (4) / total number of marbles (10) ). 4/10=2/5.

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
