Answer:
Step-by-step explanation:
This question bothers on combination. combination has to do with selection.
If 4 faculty members are chosen from total of 8 faculty members, this can be done in 8C4 number of ways.
8C4 = 8!/(8-4)!4!
8C4 = 8!/4!4!
8C4 = 8*7*6*5*4!/4!*4*3*2
8c4 = 8*7*6*5/24
8C4 = 7*5*2
8C4 =70 ways
Similarly, 5 students are to be selected from a pool of 13 students, this can be done in 13C5 number of ways.
13C5 = 13!/(13-5)!5!
13C5 = 13!/8!5!
13C5 = 13*12*11*10*9*8!/8!*5*4*3*2
13C5 = 13*12*11*10*9/120
13C5 = 1,287 ways
The total number of ways the committee can be formed is 8C4 * 13C5 = 70*1287
The total number of ways the committee can be formed is 90,090 ways
What you want to do is multiply 762 by 3, do the order of operations, and then add 143.
The order of Operations is pretty simple. Have you heard of GEMDAS? Or even PEMDAS? Well simply it is the same thing, however GEMDAS is just involving grouping symbols to make it Grouping symbols, Exponents, Multiplication or Division (which ever one comes first, do it from left to right), and then Addition or Subtraction (again which ever one comes first, do it from left to right). PEMDAS is the same thing, except it is Parenthesis, Exponents, Multiplication or Division (which ever one comes first, do it from left to right), and then last but not least Addition or Subtraction (again which ever one comes first, do it from left to right). Hope that helped! :)
