A man firing a distant target has `20%` chance of hitting the target in one shot. If P be the probability of hitting the target in atmost 'n' attempts where `20P^(2)-13P+2 le0`. then maximum value of n is.

Column I, Column II If the probability of getting at least one head is at least 0.8 in n trials, then value of n can be, p. 2 One mapping is selected at random from all mappings of the set s={1,2,3, ... ,n} into itself. If the probability that the mapping being one-one is 3/32, then the value of n is, q. 3 If m is selected at random from set {1,2,..., 10} and the probability that the quadratic equation 2x^2+2m x+m+1=0 has real roots is k , then value of 5k is more than, r. 4 A man firing at a distant target as 20% chance of hitting the target in one shoot. If P be the probabililty of hitting the target in "n" attempts , where 20 P^2-13 P+2lt=0, then the ratio of maximum and minimum value of n is less than, s. 5

A boy has 20% chance of hitting at a target. Letp denote the probability of hitting the target for the first timeat the n^(th) trial.Ifp satisfies the inequality 625p^(3)-175p+12<0, then value of n is

A man makes attempts to hit the target. The probabilty of hitting the target is (3)/(5) . Then the probability that a man hits the target exactly 2 times in 5 attempts, is

The probability of a man hitting a target is 1/2. How many xx must he fire so that the probability of hitting the target at least once is more than 90% .
