Play for Prizes!
There are three ways of changing a dollar into six coins: half, quater, dime, 3 nickels; half, 5 dimes;
and 3 quarters, 2 dimes, nickel. Information lacking, we must assign probability 1/3 to each of these.
The probability that the coin was a dime is therefore 1/3.1/6 + 1/3.5/6 + 1/3.2/6 =
4/9. Unfortunately, no one got the right answer and no prize was given out this time.
You have until the end of June to submit the answer for the question below!
AN UNUSUAL YEAR
The year 1961 had the rare property of reading the same upside-down. Of how
many years (A.D.) has this been true, and how many more will elapse before another?
