Let's imagine one situation that may be real for you. You have a tasty basket with:
- 5cookies with a cherry jam,
- 5chocolate cookies,
- 10chocolate candies,
- 5chocolate bars,
- 15biscuits,
- 10bottles of lemonade.
Calculate the probability that you will randomly pull out an item that includes chocolate, or a cookie.
We can divide our food into influential groups:
- The first one: cookies (ones with cherry jam and chocolate ones).
- The second one: is chocolate items (chocolate bars, candies, and chocolate cookies).

Follow the algorithm:
- Calculate the probability of pulling out a cookie.
- Calculate the probability of pulling out item that includes chocolate (chocolate sweet).
- Calculate the probability of pulling out a chocolate cookie.
- Calculate the resulting probability.
