1. A card is drawn at random from a standard 52-card deck. Find the probability that the card is not a queen. Of a 52 card deck, only 4 cards can be a Queen, leaving 48 other cards P=Probability P=48/52=12/13 P=12/13 or 92.3% 2. Two fair dice are rolled. Find the probability that the sum of the two numbers is not greater than 5. Random variable values are 2,3,4 Combinations equaling 2=(1,1) Combinations equaling 3=(1,2; 2,1) Combinations equaling 4=(1,3; 3,1; 2,2) Combinations equaling 5=(1,4; 4,1; 2,3; 3,2) There are 36 total combinations with the roll of dice 10 of them are <=5 Probability of a sum that is not greater than 5=10/36=5/18 or 27.8% 3. This spinner is spun 36 times. The spinner landed on A 6 times, on B 21 times, and on C 9 times. Compute the empirical probability that the spinner will land on B.

If a person is randomly selected, find the probability that his or her birthday is not in May. Ignore leap years. Ignoring leap years, a year has 365 days and May has 31 days, which means there are 334 days of the year which are NOT in May, so the probability of a birthday not being in May=334/365= approximately 91.5% 5. The chart below gives the number of vehicle tags sold in each city. One car is selected at random from the cars with vehicle tags from these cities. What is the probability that this car is from Salem? Total numbers of vehicle tags sold=12141 Number of vehicle tags sold in Salem=1773 1773/12141=197/1349 or 14.6% that the car selected is from Salem...
