Answer 1

Given that llz 3 [eveny 30 min] using poisson distribution P(x) = a la un ! (a) Ina 30min Go min ? M = 60x3 30 = 6 costone :lle= 6 9 (6) In 90 min a) = 9 P(x=5) = 0.06073 5! P(x) : OOC243 (c) In Go min - = 6 P(x=0) 28 (6) 0.00248 ::|P(x: 0) = 0.00248 (d) in 30 min la3 P(x+5)= 23 (3) 5! P(x=s) = 0.10082 = 0.10082
