Answer #1

a) Given

b) If a pair of dice is rolled , then possible outcomes =36

Favorable outcomes of sum 8 or 11 are (2,6),(3,5),(4,4),(5,3),(6,2),(5,6),(6,5)

P( 8 or 11 )=

Favorable outcomes of sum 8 or 11 or doubles are (2,6),(3,5),(4,4),(5,3),(6,2),(5,6),(6,5),(1,1),(2,2),(3,3),(5,5),(6,6)

P( 8 or 11 or doubles ) =
