Since it has a half life of 60 days, this means that every 60 days it multiplies by 0.5. Since it asks for 300 days, your equation is 500*(0.5)^5, which is 15.625 mg left after 300 days.
The probability to choose letter n is
. After drawing letter n there left 25 letters and the probability to choose the letter w is
. After drawing two letters n and w there left 24 letters and then the probability to choose letter b is
. After drawing three letters n, w and b there left 23 letters, so the probability to choose letter t is
.
Using the product rule for probabilities, you can obtain that
.
