Answer:

10.34% probability that you both pick chocolate

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question, it is not important if you or your friends picks first. So we use the combinations formula to find the number of desired and total outcomes.

Combinations Formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

Desired outcomes:

10 are filled with chocolate, and we want to pick 2. So

$D = C_{10,2} = \frac{10!}{2!(10-2)!} = 45$

Total outcomes:

The box has 30 chocolates, and 2 are picked, so:

$T = C_{30,2} = \frac{30!}{2!(30-2)!} = 435$

Probability:

$P = \frac{D}{T} = \frac{45}{435} = 0.1034$

10.34% probability that you both pick chocolate
