Since there is an equal number of odd (1,3,5) and even(2,4,6) numbers on a dice, the probability of rolling one and getting an odd number is 50%. The probability of rolling a six is about 1/6 while the probability of rolling an odd is 1/2. Finally, the probability of getting a six on the first roll and and odd on the second roll is 8/12 or about 75%. Hope this helped.
