The problem involving coin and dice, there is doubt why stop at 2 throws of coin when the sample space is {HH, HT,T1,T2,T3,T4,T5,T6}. If there is a third throw then the sample size becomes {HHH,HHT, T1,T2,T3,T4,T5,T6}. Here you see ony one T, no matter how many H before it. The sample size will always have 8 members. Like condition achived after 5 throws { HHHHH, HHHHT, T1, T2,T3,T4,T5,T6}. I wrote this down because it took me some time to comprehend this. The question being why stop at 2 throw, what if the outcome of second throw is also head ?

[@sagarmehla3781]

last question , imp doubt. What if tail comes in 3rd throw and 4th throw(HHHT) . =TH+HT + HHT + HHHT+......+infinity. =(1/2)*(2/6) + (1/2)^2 * 2/6 +.......................... infinity =(2/6)*((1/2)/1-1/2)=2/6=1/3. where I m wrong ???????
