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

12 over 91 can't be simplified.

x - 12 = 91 - 84x - 12 = 7x = 19

91/156 = (7×13)/(12×13) = 7/12

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.

Less than 50 cents.

12 x 91 = 1092

12 divided 91 = 0.13186813186813187
