By visual inspection, determine the best -fitting regression model for the data plot below . (6.3.3)

there are 6 possibilities on each dice.   therefore 6 x 6 = 36 possible outcomes.

what is the probability that the sum of the number of dots shown on the upper faces is equal to 7?  

1,6   2,5   3,4   4,3   5,2   6,1   there are 6 possible ways to get 7

6/36 = 1/6 = .

what is the probability that the sum of the number of dots shown on the upper faces is equal to 11?

5,6     6,5     there are 2 possible ways to get 11

2/36 = 1/18 = .

what is the probability that you roll "doubles" that is, both dice have the same number on the upper face?

1,1     2,2   3,3     4,4   5,5     6,6   there are 6 possible ways to get doubles

6/36 = 1/6 = .

what is the probability that both dice show an odd number?

1,1   1,3   1,5   3,1   3,3     3,5   5,1     5,3   5,5   there are 9 possible ways that both dice show an odd number

9/36 = 1/4 = .25

step-by-step explanation:

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
