(a) The number of traffic accidents that occurs on a particular stretch of road during a month follows a Poisson distribution with a mean of 9.4. Find the probability that less than four accidents will occur on this stretch of road during a randomly selected month.
(b) Twelve people apply for a job as Lecturer in a College. Eight have completed graduation and four have not. If the Principal selects five applications at random, find the probability that three are graduate and two are not.

he number of traffic accidents that occurs on a particular stretch of road during a month follows a Poisson distribution with a mean of 9.4. Find the probability that less than two accidents will occur on this stretch of road during a randomly selected month.
Solution:
P(x < 2) = P(x = 0) + P(x = 1)
Ans: 0.000860
X not X N(X) P(X) X*P(X) Σ (N) Σ (P)

Answer: 14/33
Solution:
a)
The Poisson distribution is,
P(x=x) =e-xx/x! (x=0, 1, 2, 3…)
Here =9.4
P(x<4) =? P(x<4) =P(x=0) +P(x=1) +P(x=2) +P(x=3) P(x<4) =0.000083+0.00078+0.0037+0.0115 P(x, 4) =0.01606 Solution:- b) The hyper geometric p.d is P(x=x) =kcxN-kcn-x/Ncn Here N=12 k=8 n=5 P(x=3 are graduate & two are not) =? =8c3 4c2/12c5 = 56*6/792 = 336/792 =0.4242
