Question

If a cooler contains six cola, two grape, two orange, and four lemon-lime sodas, what is the probability of selecting a cola, giving it to your friend, then selecting another cola for yourself?9/493/41/715/91

Answer 1

Given:

A cooler contains six cola, two grape, two orange, and four lemon-lime sodas

So, the total number = 6 + 2 + 2 + 4 = 14

The number of cola = 6

so, the probability of selecting a cola to the friend = 6/14 = 3/7

After selecting a cola first time the number bottels = 14 - 1 = 13

And the number of cola = 6 - 1 = 5

So, the probability of selecting a cola second time = 5/13

So, the total probability =

$\frac{3}{7}\times\frac{5}{13}=\frac{15}{91}$

so, the answer will be 15/91
