1) Amanda used a standard deck of 52 cards and selected a card at random. She recorded the suit of the card she picked, and then replaced the card. For questions 1-2 refer to the results that are in the given table. Based on her results, what is the experimental probability of selecting a heart? a) 1/52 b) 9/52 c) 1/4 d) 4/52 2) Based on her results, what is the experimental probability of selecting a diamond or a spade? a) 9/26 b) 7/52 c) 11/52 d) 0 3) What is the theoretical probability of selecting a heart? a) 9/52 b) 1/52 c) 1/4 d) 1/13 4) What is the theoretical probability of selecting a diamond or a spade? a) 1/4 b) 1/3 c) 1/13 d) 1/2 5) Dale conducted a survey of the students in his classes to observe the distribution of eye color. The table shows the results of his survey. Find the experimental probability distribution: P(blue). a) 4/20 b) 5/20 c) 3/20 d) 1/2 6) Based on the survey, what is the experimental probability that a student in Dale’s class has blue or green eyes? a) 1/40 b) 3/20 c) 1/2 d) 7/40 7) Based on the survey, what is the experimental probability that a student in Dale’s class does not have green or hazel eyes? a) 7/8 b) 1/5 c) 1/3 d) 1/4 8) . If the distribution of eye color in Dale’s grade is similar to the distribution in his classes, about how many of the 360 students in his grade would be expected to have brown eyes? a) 29 b) 58 c) 261 d) 80 9) Your sock drawer is a mess! You just shove all of your socks in the drawer without worrying about finding matches. Your aunt asks how many pairs of each color you have. You know that you have 32 pairs of socks, or 64 individual socks in four  different colors: white, blue, black, and tan. You do not want to count all of your socks, so you randomly pick 20 individual socks and predict the number from your results. Find the experimental probability: P(tan) ? ocks, so you randomly pick 20 individual socks and predict the number from your  a) 1/10 b) 4/32 c) 1/8 d) 1/16 10) Your drawer actually contains 16 pairs of white socks, 2 pairs of blue socks, 6 pairs of black socks, and 8 pairs of white socks. What is the theoretical probability of picking blue socks or white sock?  a) 20/64 b) 10/64 c) 8/32 d) 10/32
