An unfair coin is a coin that does not land heads-up and tails-up with equal probability. Let the variable X represent the number of heads-up in four tosses of an unfair coin. The probability distribution is summarized in the table below. What is the expected number of heads-up in four tosses of such an unfair coin? Express the answer as a decimal value rounded to the nearest thousandth (three digits to the right of the decimal point).
