• Dice rolled two times
  No of possibles to get odd number in first time -> 3/6
  1,3,5
  No of possibles to get even number in 2nd time -> 3/6
  2,4,6
  
  No of possible combinations {(1,2),(1,4),(1,6),(3,2),(3,4),(3,6),(5,2),(5,4),(5,6)} -->9/36
  
  So the probability is 9/36=1/4

• dices having six sides divided it into two parts as 3/6 and 3/6,then no.of possible combinations {(1,2),(1,4),(1,6),(3,2),(3,4),(3,6),(5,2),(5,4),(5,6)} -->9/36.
  so the probability is 9/36 is 1/4. so,"d" is the answer.

• dices having six sides divided it into two parts as 3/6 and 3/6,(1,3,5) & (2,4,6) then no.of possible combinations {(1,2),(1,4),(1,6),(3,2),(3,4),(3,6),(5,2),(5,4),(5,6)}=9/36.
  so the probability is 9/36 = 1/4. so,(d) is the answer.

• the probability that first rolled die is a even number is 3/6
  the probability that second rolled die is a odd number is 3/6
  =3/6 *3/6 =1/4
