You are given an unfair coin (i. e. a coin where the probability of it landing on either side is NOT 1/21/2) and told that the probability of getting at least one tails in three tosses of said coin is 26/2726/27. The probability of getting heads in one toss of the unfair coin can be expressed in the form M/NM/N, where MM and NN are relatively prime positive integers (i. e. their greatest common divisor is 1). Compute M + NM+N
