PROBABILITY JEE PYQ
-------------------------------------------------
Let the probability of getting head for a biased coin be 1/4. It is tossed repeatedly until a head appears. Let N be the number of tosses required. If the probability that the equation 64x2 + 5Nx + 1 = 0 has no real root is p/q, where p and q are co-prime, then q – p is equal to
