Susan rolled a die 1,086 times. Which of the following would be a good estimate of the number of times she rolled the number 3 o
adell [148]

Hello!

This is a problem about probability.

What we would first do is find the theoretical probability that Susan would roll the number 3 on a die.

Assuming that this is a fair six sided die, there is only one face with the number 3, and there are 6 sides, meaning that the probability that Susan rolls a 3 would be \frac{1}{6}.

Now, Susan is rolling a die 1,086, meaning that we can divide this number by 6 to find the theoretical number of times that Susan would roll the number 3 on this die.

You should get 181 times, which would be a good estimate of how many times she could roll the number 3.

Hope this helps!
