Consider the experiment of rolling a die. Find the probability of getting a number that is multiple of 3. A box contains 4 red balls, 5 yellow balls, and 7 blue balls. If a ball is picking from the box, what is the probability  of picking a red ball? A coin is thrown 3 times. What is the probability that at least one tail is obtained? In tossing coin twice, what is the probability of getting both tails? A coin is thrown 3 times. What is the probability getting exactly 2 heads?
