You can put this solution on YOUR website! The 6 sides are
:
1, 2, 3, 4, 5, 6
:
There are 3 even numbers
:
Probability of getting a three is 1/6
:
Probability of getting an even number is 3/6
:
Probability of getting a 3 or even number = 1/6 + 3/6 = 4/6 = 2/3

You can put this solution on YOUR website! P(>3) is 1/2
P(even number) is (1/2)
The joint is (1/2)+(1/2)- prob of both (4,6), which = (2/3).
Answer is 2/3
The numbers 2,4,5,6.
Answer by math_helper(2461)  (Show Source):
You can put this solution on YOUR website!
A number greater than 3 —> 4, 5, or 6
An even number —> 2, 4, 6
So the problem is asking what is the probability of rolling a 2, 4, 5, or 6.
Pr{ 2,4,5, or 6 rolled } = 4/6 = 2/3 = 0.6666...
