Question

a pair of dice is thrown simultaneously. find the probability of getting . a doublet, sum of the two dice is always 7 , an even number on the first die and a multiple of 3 on the other​

Answer 1

Answer:

doublet=(1,1)(2,2)(3,3)(4,4)(5,5)(6,6)=6/36

sum of dice is 7=(3,4)(4,3)(6,1)(1,6)=4/36

even number on dice=(2,6)(4,6)(6,2)(6,4)(6,6)=6/36
