There are only three even numbers on a "legal" six sided dice (2,4 & 6), which ever dice is designated as "first" whether rolled independently or in unison will have a 1 in 2 chance of being even.
Put another way: legal dice, designate first, 3 even, 3 odd, 50/50.
Bonus Answer: Applies to second dice also.
The probability of rolling the same number on five dice is (1/6)4, or about 0.0007716.
The probability is 11/36.
With one roll of three dice, the probability is 7/8.
1 in 6.
The probability would be 5/6 for rolling a number other than a 3.
1 out of 6.
None, because you cannot have the first or second dice: it is the first die or second die. The probability is 1/6 * 1/2 = 1/12
The probability for a normal die is 1/2.
If it is a regular dice then the probability is 3/6 that is 1/2
The probability for dice depends on how many. For a die, it is 1/3.
The answer depends on how many dice are in the SET of dice.
1/2.
