Presumably, the coin tosses are independent of one another, so

But if the coin flips are not independent, then we can't really say anything about this probability without any more information about how the flips are related...
The present value of an annuity is given by

where: PV is the current value of the annuity, P is the periodic payment, r is the apr, t is the number of compounding in one year and n is the number of years.
Thus, given that PV = $51,800; r = 7.8% = 0.078; t = 12; n = 4.

Therefore, the <span>monthly payment is $1,259.73</span>
