Question

How many times would you expect to role a 2 on a 6 sided die in 50 trials

Answer 1

The six sided die has 6 sides (with numbers 1,2,3,4,5 and 6).  That's why the probability to roll number 2 in one trial is equal to $\frac{1}{6}$.If you'll dol  50 trials, then you can expect $\frac{50}{6}= \frac{25}{3}$ times to roll number 2 (8 or 9 times).
