1) the dice has 6 numbers which are 1,2,3,4,5,6 and our of this 2,3,5 are prime numbers so the probalitty of 3/6 3 as prime number and 6 as total number in dice
2) there are only two multiple of 3 which are 3 and 6 so the proballity is 2/6
3) there two multiple of 2 which are 2 and 4 and two multiple of 3 which are 3 and 6 so in total we have 4 number which are multiples of 2 and 3 and the total of the dice is 6 so the answer is 4/6
