Louis rolled a fair six-sided die and recorded the number that was facing up on the die. He continued this for a total of 80 rolls. The table shows the frequency of each number rolled.

Outcome 1 2 3 4 5 6
Frequency 15 11 14 15 10 15


Based on the table, what is the experimental probability that the number rolled was odd?
41 over 80
39 over 80
5 over 12

Answer:

Explanation:

The experimental probability of rolling an odd number is the frequency of rolling an odd number divided by the total number of rolls:

P(odd) = (15 + 14 + 10) / 80

P(odd) = 39/80

So the experimental probability of rolling an odd number is 39/80. Answer: 39 over 80.

Answer:

39/80

Explanation:

Take all the frequencies combined we get 80

15 + 11 + 14 + 15 + 10 + 15 = 80

80 will be our denominator.

---------------

Now lets list the outcomes that are odd

1, 3, 5

----------------

Now we will add all the frequencies together that are odd

15 + 14 + 10 = 39

-----------------

We have our numerator

Take both the denominator and numerator

to create a fraction.

-------------------

We will get 39/80

Thank me later!
