John had 8 marbles and 4 red marbles in the bag. He took 1 marble from the bag and then replaced it and then took a second marble. What is the probability that john gets a red marble and then a red marble again? A: 1/9

B: 3/4

C: 1/3

D: 1/11

1/4

Step-by-step explanation:

P(red,red) = 4/8 x 4/8 = 1/2 x 1/2 = 1/4

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
