Step-by-step explanation:

i dont think the a b and c are multiple choice they are steps to solve the problem

the events in the problem are rebecca approving couch 85% and her roomate approving the couch 50%

a: rebecca approving couch 85%

b: roomate approving the couch 50%

probability rebecca and roommate approves is percentages multiplied.

85% times 50% = 0.85*0.5

=0.425

42.5%

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )
