You can put this solution on YOUR website! six stand up comics A,B,C,D,E, and F are set to perform at a single event, order to be determined randomly. Find the probability that C will perform third and D will perform fourth!
-----------
# of ways to succeed = ?:
Perform 1st: 4 choices
Perform 2nd: 3 choices
Perform 3rd: 1 choice
Perform 4th: 1 choice
Perform 5th: 2 choices
Perform 6th: 1 choice
-----------------------------
Number of ways to succeed = 4*3*1*1*2*1 = 24
=============================
Number of unrestricted orders: 6! = 720
=============================
Probability that C will be 3rd and D will be 4th = 24/720 = 0,0333,,,'
