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?

Express your answer in simplest form.

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

The answer has to be a fraction.

youngstudier · Answer

4 and 6?

@MonKiwi

campbell_st · Answer

so there were 4 3s and 6 6s... 

great what was the total number of rolls..?

youngstudier · Answer

10
I'm not sure over what number though.

campbell_st · Answer

add the number of times each outcome occurred...

youngstudier · Answer

Oi vey, I mean the number of times 3 and 6 occured is 10..

campbell_st · Answer

or... how many rolls made up the experiment

youngstudier · Answer

Well, I added up the numbers each occured, and got 40, so I'll assume that's how many rolls.

youngstudier · Answer

So would the fraction be 1/4 ?

campbell_st · Answer

great so 

P(3 or 6) = 10/40

now simplify the fraction

campbell_st · Answer

and you are correct
