hello sir and madams! could you please solve these tasks step by step? I am in the exam. Thanks a lot! ))

1. Discrete distribution for X is given by the following table: Probability p 0.2 0.2 0.5 Value X 20 10 20 Find distribution function fa) and median M Calculate expectation value M variance (dispersion) D standard error o(X), asymmetry coefficient AsC) and excess Ex 2. Calculate multiplier k. Find mode Mo(x), median Me(x), expectation value MA), variance (dispersion) Dam) and standard error o(x) for continuous distributions having the given probability densities x

Explanation / Answer

You have asked more than one question, I am answering all the parts of question 3.

(3)

Total chips = 20+5+15 = 40

(a)

P(2 processors) = 5C2/40C2 = 1/78 = 0.0128

(b)

P(at least one processor) = 1 - P(no processor)

P(no processor) = 35C2/40C2 = 119/156 = 0.763

So,

P(at least one processor) = 1 - 0.763 = 0.237

(c)

P( amplifier and memory block) = (20C1*15C1)/40C2 = 5/13 = 0.384

(d)

P(no amplifiers) = 20C2/40C2 = 19/78 = 0.243
