Oh, dude, let me do some quick math in my head... so, like, 15 goes into 91 six times with a remainder of 1. So, there you have it, 15 goes into 91 six times. Math can be fun, right?
If there are 14 rows in the triangle, then there are 14*(14-1)/2 coins in the arrangement, i.e. 91 dimes. To find the value of the collection, simply multiply by the value of a dime. I believe this is 10 cents, so the coins are worth 910 cents, or $9.10.

The probability of flipping 91 coins and getting a head 91 times in a row is 1/291 or (1/2)91 or 4.039E-28. The (1/2)91 is when there is exactly 91 coin tosses or n = 91. As the number of trials increases so does the probability of at least 1 run of length 91. The average number of coin flips to see 91 in a row is 4.951760157141521e+27
