Answer:
Step-by-step explanation:
Let X be the no of defective components produced by a certain process in one day
X is Poisson with parameter = 20
Y = no of components that can be repaired
Since each component to be repaired is independent of the other Y is Binomial with p =0.60
a)
b) P(Y = 10)= Binomial prob (15,0.6) for y =10
=
Here no of repairables X is binomial.
c) Prob for 15 produced and 10 repairable = product of a and b
= 0.009603
