Answer:
1. 0.0000454
2. 0.01034
3. 0.0821
4. 0.918
Step-by-step explanation:
Let X be the random variable denoting the number of passengers arriving in a minute. Since the mean arrival rate is given to be 10,

1. Requires us to compute

2. We need to compute 




3. The expected no. of arrivals in a 15 second period is =
. So if Y be the random variable denoting number of passengers arriving in 15 seconds,


4. Here we use the fact that Y can take values
. So, the event that "Y is either 0 or
1" is a sure event ( i.e it has probability 1 ).

Answer:
B=25
Step-by-step explanation:
b=2(10)^2(10-5)/10(10
b=2(100)(5)/100
b=(200)(5)/100
B=2500/100
B=25
