Answer:
Step-by-step explanation:
In a coin toss the probability of tossing a head is 0.5 (50% head/50% tails)
If n is the number of rounds and 2n the number of coins tossed (one for each player), the probability of having m heads tossed is:
R is the number of cases (combination of coins tossed) that gives a m number of heads. Each case has a probability of 
so:
<u>For example, to toss 4 heads in 5 rounds: </u>
so.. the left-hand-side does indeed simplify to x+7, so the equation does check out.
however, notice something, for the equation of x+7, when x = 6, we get (6) + 7 which is 13.
BUT for the rational, we get
so, even though the siimplification is correct, the rational or original expression is constrained in its domain.
