Answer:

The contestant should not play.

Explanation:

As per the given question, their current winning is $1 million.

The probability of the guessing to be true is 50% =
(50)/(100) = (1)/(2).

There is also a possibility of 50% to be wrong, which can reduced the winning amount to $500,000 that is the half of the current amount.

Hence, the contestant should not play.
