Question

If you roll a six sided die, what is the probability of getting ...
 a multiple of 2 
  a composite number 
 a odd number

phi · Answer

probability is the number of rolls that match your condition divided by the total number of possible rolls.   A roll must end up with one of (1,2,3,4,5,6)  (6 events)
how many are a multiple of 2?  2,4,6 (3 events) so 3/6 or 1/2 is the probability

a composite number:  those not prime.
