Question 246734: Number of students passing
Pass-46
Fail-37
Total-83
From the data above, what is the probability of passing? p=?
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, (2) that more than Y number of student pass, and (3) the probabilty that Z number or fewer students will pass this term.
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 probalities have been calculated and explained correctly.

You can put this solution on YOUR website! 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.
======================================
