Six friends decide to share a big cake. Since all ofthem like the cake, they begin quarreling who gets to
first cut and have a piece of the cake. One friend suggests that they have a blindfold friend choose from well
shuffled set of cards numbered one to six. You check and find that this method works as it should simulating a
fair throw of a die. You check by performing multiple simultaneous trials of picking the cards blindfold and
throwing a die. You note that the number shown by the method of picking up a card and throwing a real world
die, sums to a number between 2 and 12. Which total would be likely to appear more often – 8,9 or 10?
a) 8
b) All are equally likely
c) 9
d) 10

• 8 is appeared in (13-8) ways means =5 ways
  9 in (13-9 ) ways =4 ways
  similarly 10 we get in 3 ways
  so ans is 8

• 8 is appeared more
  8-5(2+6,6+2,3+5,5+3,4+4)
  9-4(3+6,6+3,4+5,5+4)
  10-3(5+5,4+6,6+4)

• ans- 8 as there are 5/36 chances for the sum to be 8 whereas for sum to be 9 there are 4/36 chances and for the sum to be 10 there are 3/36 chances
