Four fair coins are tossed once. Calculate the probability of having equal heads and tails.

Answer Details

When tossing a coin, there are two possible outcomes: heads or tails. Since we are tossing four coins, there are \(2^{4} = 16\) possible outcomes. We want to find the probability of having an equal number of heads and tails. The possible outcomes where we have an equal number of heads and tails are as follows: HHTT, HTHT, THHT, THTH, HTTH, TTHH. There are six such outcomes. Therefore, the probability of having an equal number of heads and tails is \(\frac{6}{16} = \frac{3}{8}\). So the answer is.
