A computer lab has two printers. Printer I handles 40% of all the jobs. Its printing time is Exponential with the mean of 2 minu

tes. Printer II handles the remaining 60% of jobs. Its printing time is Uniform between 0 minutes and 5 minutes. A job was printed in less than 1 minute. What is the probability that it was printed by Printer I?

Answer:  0.3042

Explanation:

Let A  and B are the events to that job done by Printer I and Printer II respectively.

Given : P(A)=0.40    P(B)=0.60

Printing time of Printer I is Exponential with the mean of 2 minutes.

i.e. average number of job done in one minute:\lambda=\dfrac{1}{2}

The cumulative distribution function (CDF) for exponential distribution:-

F(x)=1-e^{-\lambda x}, where \lambda is the mean.

Then, the cumulative distribution function (CDF) for Printer I:-

P(X|A)=1-e^{-\dfrac{1}{2} x}

i.e. P(X

Printing time of Printer II is Uniform between 0 minutes and 5 minutes.

The cumulative distribution function  (CDF) for uniform distribution in interval (a,b) :-

F(x)=\dfrac{x-a}{b-a}

Then, P(X|B)=\dfrac{x-0}{5-0}=\dfrac{x}{5}

i.e. P(X

Now, the required probability :-

\text{P(A}|X

Hence, the required probability = 0.3042

for (int i = 0; i <array.length; i ++) {  

   System.out.print (array [i]);  

}

Enhanced for loop

for (String element : array) {

   System.out.print(element);

}
