Answer:


(250)/(3)

Step-by-step explanation:

you can expect to get a 3 (theoretically) 1 time every 6 times you roll. A 1/6 chance.

Here's the equation:


(1)/(6) =(x)/(500)

cross multiply (i think that's what it is called)

500=6x

divide by 6 on both sides:

x=
(250)/(3) or approx 83 times.

Hope this helps! Lmk if u have more questions <3
