Question

When rolling a number cube 500 times, how many times you expect to get a 3?

Answer 1

`(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
