Question

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

Answer 1

Answer:

$\frac{250}{3}$

Explanation:

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

Here's the equation:

$\frac{1}{6} =\frac{x}{500}$

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

500=6x

divide by 6 on both sides:

x=$\frac{250}{3}$ or approx 83 times.

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