P(total of 3) = 2C1 * (0.5) * (0.5) = 2 * 0.25 = 0.5 = 1/2
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:
Rational
