There are 28 total possibilities the two cards can be drawn Therefor there is a probability that the cards drawn will equal a sum of 10. b) Let A represent the probability that the sum of the numbers will be greater then 14 There are 16 outcomes that will have a sum greater then 14 or 0.571 There is a 57.1% chance that there will be a sum greater then 14 c) The drawing of the two cards from the 8 at random are mutually exclusive events. The drawing of one card has nothing to do with the drawing of the other card. Key Questions Lesson 13 51.a) independent: the first roll will not affect the second roll and vice versa b) dependent: not having the car serviced would probably make the car die faster than having the car regularly serviced. The life of the car will depend on the service c)The first face card drawn in an independent event. However, the 2nd face card drawn is a dependent event because if one face card is already drawn the chance of drawing a second face card is lowered. d) independent: a person’s height has nothing to do with the whether or not they can do math and vice versa 52. Let A represent first-year students that live in college dormitories Let B represent graduation rate of first year college students a) Therefor 0.3 or 30% of first year students will live in a dormitory and graduate college. b) p’(A)=1-p(A) =1-0.40 =0.60 Therefor there is a 45% chance the students will not live in a

f) To find the probability of each of these answers you would start by dividing the possible successful outcomes by the total number of possible outcomes. In the example E, the question asked for anyone except an administrator, therefore, taking the total amount of people minus the administrator will give you a category for those you want to have picked. After that, you would continue as if you had the successful possibilities divided by all possible

What is the probability of rolling a four in the gambling dice game of craps (given two six sided dice)? 3/36 or 8.33%. What is the probability that a player can roll a four 3 times in a row (assume that rolling the dice each time does not affect the outcome of the next roll)? 3/36 x 3/36 x 3/36 = 27/46656 = 3/5184
