Answer:
S= {8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 }
event F= {10 , 11 , 12 , 13 , 14}
event G= {14 , 15 , 16 , 17}
a) List of outcomes in F or G
answer;
(F or G) = { 10 , 11, 12 , 13 , 14 , 15 , 16 , 17}
b) P ( F or G) = by counting the number of outcomes in F or G
Ans ( F or G) = No. of outcomes in ( F or G) / Total no. of outcomes
= 8/12 = 2/3
c) P ( F or G) using general addition rule
Ans P (F or G) = P(F) = P(G) - P( F and G)
= 5/12 + 4/12 - 1/12
= (5+4-1)/12 = 8/12 =2/3
