Exercises

1. A coin was tossed 8 times by each person in a group of people. The number of people, , who got a total of heads were as follows:

Based on this experimental data, determine the (empirical) probability of obtaining heads out of 8 coin tosses for . Find the expected number of heads given the above data. Compare your results with the expected value of heads in a theoretical distribution in which the probability of H and T are equal.



2. Find the probability of randomly selecting 4 aces from a well-shuffled deck of 52 cards. Find the probability of randomly selecting 4 hearts (of any value) from a well-shuffled deck of 52 cards. (Note: a full deck of cards contains 13 hearts.) What is the probability of randomly selecting the sequence of cards of value “King”, “Queen” Jack” (of any suit or combination of suits) from a well-shuffled deck of 52 cards.
