The proportion is not mentioned, however "A university discovered that of its students withdraw without finishing the basic statistics course." Assume that p of the students drop out of the course before finishing. There are a total of students enrolled in the programme nXBin(n,p)Part (a): Calculate the likelihood that or fewer people will withdraw (to 4 decimals) Here, let's say that we need to determine the likelihood that fever or m will disappear. According to the definition of the mass function of X,P(X=x)=(nx)×px×(1p)nx
P(Xm)=[P(X=0)+P(X=1)+...+P(X=m1)]Part (b): Determine the likelihood that a specific withdrawal will occur (to 4 decimals). The precise amount is not provided here either. Let's now presume that M will really withdraw. The likelihood that m' will withdraw precisely:P(X=m)=(nm)×px×(1p)nmCalculate the likelihood that more than M people will withdraw in part (c) (to 4 decimals). Assume that M is the necessary number. The likelihood that M or more people will withdraw:P(X>M)=1P(XM)
