Elementary my friend.
The probability of getting a 6 is .2. As such, if we roll 300 times, we expect .2*300=60 sixes to appear.

Since there is a 20% chance of the dice rolling a 6 we can assume every 100 rola u will roll a 6 20 times. Since u roll it 300 times the answer should be 20*3 which is 60
