Question
Maryland lottery In the Maryland
Pick-3 Lottery, three random digits
are drawn each day. A fair game de-
pends on every value (0 to 9) being
equally likely to show up in all three
positions. If not, someone who detects
a pattern could take advantage of that.
The table shows how many times
each of the digits was drawn during a
recent 32-week period, and some of
them—4 and 7, for instance—seem to
come up a lot. Could this just be a re-
sult of randomness, or is there evi-
dence the digits aren’t equally likely
to occur?
