Compute the probability that or fewer will withdraw (to 4 decimals). b. Compute the probability that exactly will withdraw (to 4 decimals). c. Compute the probability that more than will withdraw (to 4 decimals).

The proportion is not mentioned, however &quot;A university discovered that of its students withdraw without finishing the basic statistics course.&quot; Assume that p of the students drop out of the course before finishing. There are a total of students enrolled in the programme nX∼Bin(n,p)Part (a): Calculate the likelihood that or fewer people will withdraw (to 4 decimals) Here, let&#039;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×(1−p)n−xP(X≤m)=[P(X=0)+P(X=1)+...+P(X=m−1)]Part (b): Determine the likelihood that a specific withdrawal will occur (to 4 decimals). The precise amount is not provided here either. Let&#039;s now presume that M will really withdraw. The likelihood that m&#039; will withdraw precisely:P(X=m′)=(nm′)×px×(1−p)n−mCalculate 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&amp;gt;M)=1−P(X≤M)
