Question

The table shows the results of rolling a number cube, with sides labeled 1 through 6, several times.

What is the experimental probability of rolling a 3 or a 6?

Enter your answer as a fraction in simplest form.

Outcome:  Number of times outcome occurred:
1,               10
2,                6
3,                4
4,                8
5,                6
6,                6

Answer 1

1st, add outcomes:10+6+4+8+6+6=40
2nd, add the outcomes of the numbers you want:(3)->4 (6)->6 4+6=10
3rd, put them over each other
`(Numbers You Want)/(Total Outcomes)`:
`(10)/(40) = (1)/(4)`
