Can you use a tree diagram to calculate the probability that the sum of the dice is an even number?

Yes, it is possible, but it is far easier to simply sit and think about the problem for a bit. For the sum of two numbers to be even, their parities must be the same (i.e. they must either be both even or both odd).
If you roll a die, and it comes out to be even, then the other die must also be even for the sum to be an even number. The same is true if the die comes out to be odd. Then you can make sort of a generalized tree diagram, where you group outcomes together. Then the two possible outcomes for a die are even and odd. If you construct a tree diagram, it will split into two branches, with one even and the other odd. The same will occur for each of these branches, with a total of four branches at the end. Half of them will satisfy your requirement; that is, in half of all outcomes the sum of the dice is an even number.
Sorry for the rather unnecessarily verbose answer.

What is the probability of rolling an even number with 3 dice?
With one roll of three dice, the probability is 7/8.
What is the probability that the sum of the dice is odd and both dice show the number 3?
The probability is 0. If both dice show the number 3 then the sum is 6 which is not odd.
What is the probability of rolling a dice and getting an odd number?
The probability of getting an odd number in a single throw of a fair die (not dice!) is 1/2.The probability of getting an odd number in a single throw of a fair die (not dice!) is 1/2.The probability of getting an odd number in a single throw of a fair die (not dice!) is 1/2.The probability of getting an odd number in a single throw of a fair die (not dice!) is 1/2.
What is the probability of getting 4 of a kind if 5 identical dice are tossed simulataneously?
If they are fair dice, the probability is 0.0032If they are fair dice, the probability is 0.0032If they are fair dice, the probability is 0.0032If they are fair dice, the probability is 0.0032
What is the probability of rolling a number less than a 6 on a set of dice?
The answer depends on how many dice are in the SET of dice.
You roll 2 dice You can use a Venn diagram to calculate the probability that the sum of the dice is a prime number?
false.
What is the probability of rolling an even number with 3 dice?
With one roll of three dice, the probability is 7/8.
When rolling five dice what is the probability that all 5 dice will be the same number?
The probability of rolling the same number on five dice is (1/6)4, or about 0.0007716.
What is the probability that the sum of the dice is odd and both dice show the number 3?
The probability is 0. If both dice show the number 3 then the sum is 6 which is not odd.
What is the probability of rolling a dice and getting an odd number?
The probability of getting an odd number in a single throw of a fair die (not dice!) is 1/2.The probability of getting an odd number in a single throw of a fair die (not dice!) is 1/2.The probability of getting an odd number in a single throw of a fair die (not dice!) is 1/2.The probability of getting an odd number in a single throw of a fair die (not dice!) is 1/2.
You roll 2 dice What is the probability that the sum of the dice is prime and both dice show the number 6?
The probability is 0 since if both dice show the number 6, their sum is 12 which is not a prime.
What is the probability of having the same number when rolling a dice twice?
If it is a regular dice then the probability is 3/6 that is 1/2
What is the probability of rolling a number greater than 4 On a dice?
The probability for dice depends on how many. For a die, it is 1/3.
What is the probability of getting at least one prime number in two dice?
The probability of getting at least one prime number in two dice is 3/4.
What is the probability of throwing a dice and getting the number 1?
Depends on the dice! There are six sides on a dice. The number 1 is on on out of the six sides to the probability of getting a one is 1/6 which is equal to .16666 or 16.6%
How do you do probability of independent events?
The answer depends on what you mean by "do". Does it mean calculate individually, calculate the probability of either one or the other (or both), calculate the probability of both, calculate some function of both (for example the sum of two dice being rolled)?
What is the probability of getting 4 of a kind if 5 identical dice are tossed simulataneously?
If they are fair dice, the probability is 0.0032If they are fair dice, the probability is 0.0032If they are fair dice, the probability is 0.0032If they are fair dice, the probability is 0.0032
