There is a fifty percent chance of the coin landing on "heads" each time it is flipped.
However, flipping a coin 20 times virtually guarantees that it will land on "heads" at least once in that twenty times. <span>(99.9999046325684 percent chance)

You can see this by considering two coin flips. Here are the possibilities:
Heads, heads.
Heads, tails.
Tails, tails.
Tails, heads.
You will note in the tossing of the coin twice that while each flip is
fifty/fifty, that for the two flip series, there are three ways that it
has heads come up at least once, and only one way in which heads does
not come up. In other words, while it is a fifty percent chance
for heads each time, it is a seventy five percent chance of seeing it
be heads once if you are flipping twice. If you wish to know
the odds of it not being heads in a twenty time flip, you would multiply
.5 times .5 times .5...twenty times total. Or .5 to the twentieth
power. That works out to a 99.9999046325684 percent chance of
it coming up heads at least once in the twenty times of it being
flipped.
There is a clear bias. It is important however to not look at how many women got promoted with respect to men but which proportion of each subset got promoted. In the man files, 21/24 got promoted; this is a very high percentage, equal to 87.5%. Nonetheless, regarding women, 14/24 got promoted, 58,3%, barely over half of them. Hence, we conclude that there is a significant bias that favors male workers.
