The Prime Number Riddle
Two hundred people in an auditorium are asked to think of a single digit number from 1 to 9 inclusive and write it down. All those who wrote down a prime number are now asked to leave. Ninety people remain behind in the hall. How many of these are expected to have written down an odd number?
Hint: Remember that 1 is not a prime number.
Those that remain behind must have written {1,4,6,8,9} and from this only {1,9} are odd. The probability of an odd number is thus 2/5.
Expected number of odds is 2/5 * 90 = 36 Did you answer this riddle correctly?

Light First Riddle
Hint:
Pongo And Perdita's Litter
Hint:
In the movie 101 Dalmatians, the dalmatian couple Pongo and Perdita originally had 15 puppies of their own.
As the story progresses, they were able to rescue 99 puppies from Cruella de Vil. (Pongo is the 100th and Perdita is the 101st)
It can be a source of confusion for many, especially those who have read the book, because in the book, Perdita was not Pongo's wife. His wife was referred to as Mrs. Pongo. Perdita is another dalmatian parent who lost her litter to Cruella De Vil. Although not specified in the book, it was believed that she had 8 puppies in her litter.
