problem_activity: Problem 1
You are in a diner and want to know if choosing cream or sugar are independent events, that is, if one depends on the other. Below is a Venn diagram that represents the number of people in the diner one morning. A random person is chosen.

Is this random person more likely to have cream in his coffee if he has sugar? Calculate the probability.

Problem 2
A coin is tossed and a single six-sided die is rolled. If landing on heads is represented by
$$H$$
and rolling a
$$3$$
is represented by
$$R$$
, determine if the following is true:
$$P(H \space and \space 3)=P(H)\cdot P(3)$$
