Answer:
Step-by-step explanation:
Here X the no of children suffering from hookworm treated and recovered is binomial because
a) Each child is independent of the other
b) There are only two outcomes
c) The probability for any child to recover is constant as 90% = 0.9
X is Bin (20,0.9)
a) Prob that all 20 will be cured
=P(X=20)=
b) Prob all but 1 will be cured=
c) Prob exactly 18 will be cured

d) Prob exactly 90% will be cured.

Yes you are right from what i seen
Answer:
(a) 0.01029 (b) 4.167 customers (c) 0.4167 hours or 25 minutes (d) 0.5 hours or 30 minutes
Step-by-step explanation:
With an arrival time of 6 minutes, λ=10 clients/hour.
With a service time of 5 minutes per transaction, μ=12 transactions/hour.
(a) The probability of 3 or fewer customers arriving in one hour is
P(C<=3)=P(1)+P(2)+P(3)


(b) The average number of customers waiting at any point in time (Lq) can be calculated as

(c) The average time waiting in the system (Wq) can be calculated as

(d) The average time in the system (W), waiting and service, can be calculated as
