Answer 1

The favouring non-favouring of unmanned drones a bernoulli variate and the distribution of us adulfs dato about dato about favouring non-favouring of unmanned drones follows the binomial distribution. or We have n - 12 p = 371 0.37 we know the probability mass function of binomial distribution is non pen) = en Pr (1-P) Answer - (a) - we have to find p(3) P(3) = 12 co phu - p2-3 P(3) = 1262 (0.37)3 (1-0.37) P13) 220 X o oso653 x 0.01563381 P(3) = 0.174

Answer (6) :- we have to find & (274) p (2714) = 1- pn 44) : 1- [P(n=0) + P(n=1) + P (n=2) & PM=3)] =1-[1%(0.30)*(1-0,37) 726,10.37)*(1-0.37) =1-(0.00391 +0.02755047+ 0,088992392 +0.17422J 12:37 + - 1-0.29467 P(2714) = 0.70S

Answer-(C) 8- we have to find p(x48) pen<8) = 1- P(178) = 1 - (POE 8) + P Q =9)+ Pf=10) + PRENI+PG 2123] 7- [ºs, 0.2061-0.39/41 266.379 (1 -0.37) 2 - 7 (0.3+)'(-0.37)4972 7 12 (htt 1, 12-12 1-(0.027389+0,007149+0,00125963+0.00013451 +0.0000066 - 1-0.03594 IP 248) = 0.964
