Express as a fraction the probability that the outcome for rolling two number cubes has a sum less than 7. Probability COURSE 3 LESSON 6-9 Make a table to find the sample space for rolling two number cubes (1,1)(2,1)(3,1)(4,1)(5,1)(6,1) 2(1,2)(2,2)(3,2)(4,2)(5,2)(6,2) 3(1,3)(2,3)(3,3)(4,3)(5,3)(6,3) 4(1,4)(2,4)(3,4)(4,4)(5,4)(6,4) 5(1,5)(2,5)(3,5)(4,5)(5,5)(6,5) 6(1,6)(2,6)(3,6)(4,6)(5,6)(6,6) (1,1)(2,1)(3,1)(4,1)(5,1)(6,1) 2(1,2)(2,2)(3,2)(4,2)(5,2)(6,2) 3(1,3)(2,3)(3,3)(4,3)(5,3)(6,3) 4(1,4)(2,4)(3,4)(4,4)(5,4)(6,4) 5(1,5)(2,5)(3,5)(4,5)(5,5)(6,5) 6(1,6)(2,6)(3,6)(4,6)(5,6)(6,6) Out of the 36 possible outcomes, the 15 outcomes shown in red have a sum less than 7. So, P(sum less than 7) =, or

What is the probability (as a fraction) of there being at least 1 male kitten in a litter of 4 kittens? Express the probability as a fraction. Probability COURSE 3 LESSON

(continued) Probability COURSE 3 LESSON 6-9 P(at least one male) = number of outcomes with at least one male kitten total number of possible outcomes with four kittens =Substitute. 6-9

Probability 1.A 6-sided number cube has the numbers 1, 2, 3, 4, 5, and 6 on its faces. What is the probability of rolling a number less than 5? Write your answer as a fraction and as a percent. 2.Find the sample space for tossing two coins. Then find P(0 heads). COURSE 3 LESSON 6-9 HH, HT, TH, TT; 25% ; 66 %
