Question : 16

Total: 40

A crate of soft drinks contains 10 bottle of Coca-Cola 8 of Fanta and 6 of Sprite. If one bottle is selected at random, what is the probability that it is Not a Coca-Cola bottle?

$\frac{5}{12}$
$\frac{1}{3}$
$\frac{3}{4}$
$\frac{7}{12}$

Solution:

Coca-Cola = 10 bottles, Fanta = 8 bottles, Spirite = 6 bottles

Total = 24

P(Coca-Cola) = $\frac{10}{24}$ ; P(not Coca-Cola)

1 - $\frac{10}{24}$

$\frac{24 - 10}{24} = \frac{14}{24} = \frac{7}{12}$
