A six-sided number cube is rolled. Find the probability of rolling a 3 or a number greater than 4.

A.1/8
B.1/6
C.1/2
D.2/3

Answer 1

There are 6 sides and numbers in the cube. (1,2,3,4,5,6)
Probability of rolling a 3 or a number greater than 4: there are 2 numbers greater than 4 (5 and 6) and one other number (3). In total, there are 3 numbers here.

So the probability of rolling 3 numbers out of 6 is 3/6, which can be simplified to 1/2.

Answer 2

Well, there are 6 sides.

There are also 6 numbers: 1, 2, 3, 4, 5, 6

Okay, so the probability of rolling a 3 is 1/6 because that is just one number of the 6.

Okay, number greater than four are 5 and 6, and if you add 3 to that you get 3/6, or 3 out of 6 numbers.

If you simplify 3/6 you get 1/2.

Hope this helps!
