Question 246734
Number of students passing 
Pass-46
Fail-37
Total-83
From the data above, what is the probability of passing? p= 46/83
----------------------------------------------------------------------
If there are 20 students in the class this term and we assume the same passing rate, formulate a problem that(1) provides the probability that exactly X number of students pass this term, 
Binomial Problem with n = 20, p = 46/83 ; x students pass
-------------------------------------------------------------------

(2) that more than Y number of student pass, and 
Binomial Problem with n = 20, p = 46/83 ; y+1 <= x <= 20 pass
-------------------------------------------------------------------

(3) the probabilty that Z number or fewer students will pass this term.
Binomial Problem with n=20, p = 46/83 ; 0 <= x <= z pass
===================================================================
 
The value for X,Y, and Z are what you must decide and then solve your problem. In reviewing the work of your classmates make sure that each of these probabities have been calculated and explained correctly.
---------------------
I'll let you find x,y, and z.
