Answer:

option c, 70%

Step-by-step explanation:

80 total keychains

24 are blue

80 total keychain - 24 blue keychain = 56 non blue key chain

the probability of chooising one of these 56 keychain is

56 / 80 = 0.70

0.70 x 100% = 70%

OR

the probability of chooising a blue keychain is

24 / 80 = 0.30

1 - 0.30 = 0.70           (1 = the total amount)
