It seems i've made numerical mistake.The sum of the numerator is 1/8. So final answer is 1/4. Sorry friends.

Last question. We need to find the fraction. In the denominator is the probability of "at least one multiple of 3". This is the infinite series with sum 1/2. In the numerator there is the probability of intersection of " a tail and at least one multiple of 3". This is also infinite series with sum 1/4. Devide second by first and you'll get 1/2.

sir... in the lasst ques.... its given that atleast on one dice 3 should come okk??? so suppose on one dice 3 came... so in nxt case when it will be 3, 1 then coin is tosssed so we can get a tair in dat case.... if we get 3, 3 dn again we'll get a chance and then it can be 331 dn also we'll get a cance to throw a coin so why is probablity zero???? :'( sorrry i didn't get...
