Answer :

Answer:

Completed table in image

a) 5/9

b) 1/3

Step-by-step explanation:

Completed table is shown; the numbers in the cells are the sums of both spins

Sample Space is S = {4, 6, 6, 8, 9, 9, 11, 11, 14}

Total elements = size of sample space = 9

a) P(even number total)
The even number totals are {4, 6, 6, 8, 14}  
Thus there are 5 possible even number outcomes
P(total is an even number)
= Number of even total outcomes/Sample Space Size

= 5/9

b) Total not more than 6
==> Total is 6 or less
==> Total = 4, 6, 6  (3 possible outcomes )
P(total not more than 6) =  3/9 = 1/3
