Question 1047072: A biased tetrahedral die with faces labelled 1,2,3 and 4 is rolled once. The chance of getting a '3' is twice that of getting a '1' . The chance of getting a '2' is thrice that of getting a '3' . There is an equal chance of getting a'2' and a '4' . Find the probability of getting a prime number.

Hi
1 x 1/15
2 6x 6/15
3 2x 2/15
4 6x 6/15
15x = 1
P(Prime) = 9/15
