two envelopes problem
name
A
puzzle
of
this
kind:
"You
are
given
two
indistinguishable
envelopes,
each
containing
money;
one
contains
twice
as
much
as
the
other.
You
may
pick
one
envelope
and
keep
the
money
it
contains.
Having
chosen
an
envelope
at
will,
but
before
inspecting
it,
you
are
given
the
chance
to
switch
envelopes.
Should
you
switch?"
Because
you
stand
to
gain
twice
as
much
money
if
you
switch
while
risking
only
a
loss
of
half
of
what
you
currently
have,
it
is
possible
to
argue
(fallaciously)
that
it
is
beneficial
to
switch.

A puzzle of this kind: You are given two indistinguishable envelopes, each containing money; one contains twice as much as the other. You may pick one envelope and keep the money it contains. Having chosen an envelope at will, but before inspecting it, you are given the chance to switch envelopes. Should you switch?
Because you stand to gain twice as much money if you switch while risking only a loss of half of what you currently have, it is possible to argue (fallaciously) that it is beneficial to switch.
