a) Suppose that Game store in Polokwane donated a lot of 8 computer sets thatincludes 3 which are malfunctioning or defective. If 4 of this computer sets arechosen at random for delivery to a school.i)What will be the probability mass function of a random variable Y?ii) What will be the expected value of Y?b) A master's student, Mr Nkandimeng Ledwaba's task this semester is to contact theResearch Office at the University of Limpopo for support for the university's NationalResearch Fund (NRF). Studies conducted in South Africa and elsewhere, point outthat the probability that each of the his calls is answered is What will be theprobability that the second call to be answered on one particular day is his sixth call?c)i)Find the value of k which make the following function a pdf(15 Y - 2syso6464fV) = {3+ ky 0
