You have a bag of marbles that contains, 7 red, 4 green, and 5 yellow marbles. What is the probability that you would pull out a green marble,
REPLACE it, AND then pull out another green marble. Give your answer as
a lowest term fraction.

i hope my answer help you

Step-by-step explanation:

the probability to pull out a green marble=4/16 ( simplest form =1/4)

the probability to pull out a green marble after replace the previous marble=3/15 (simplest form =1/5)

we know that

applying the law of sines

°

so

∠j=18°

∠k=29°

∠l=180-(18+29)=133°

the answer part a) is

the measure of angle k is  ≈29°

part b)  the measure of angle k could also be

(180-29)=151°

so

∠j=18°

∠k=151°

∠l=180-(18+151)=11°

the answer part b) is

the measure of angle k could also be 151°
