Given that Mandvil has one standard quarter and one special quarter with a Head on both sides, and he selects one of these two coins at random, and without looking at it first, he flips the coin three times, to determine, if he flips a Head three straight times, what is the probability that he selected the special quarter, the following calculation must be made:

1 - (standard quarter) = X
1 - (0.50^3) = X
1 - 0.125 = X
0.875 = X
0.875 x 100 = 87.5

Therefore, the probability that he selected the special quarter is 87.5%.

So, 1725 would be 1 and a half month's pay of rent.

The equation would be 1725 divided by 1.5 since that would get us what the two friends paid for one month of rent. Let r= rent.

1725/1.5= r

1725/1.5= 1150

So, rent would equal $1150.

I hope this helps!
