Question 463143: you work for a small corporation which has 3 field representatives A,B,C who telephone the home office for various reasons. Field rep A makes 45 percent of the calls, and rep B and C make 40 snd 15 percent of the calls, respectively. if A calls, then there is a 4 percent chance that she will ask for the VP in charge of sales for help in closing a deal, whereas if B or C, then there is a 10 percent or 22 percent chance of their asking for assistance. One of the field representatives calls and asks for the VP's help. Because you were on your lunch break , you didnt bother to write down the field reps name and you now cant remember who called. assuming you must relay the request whom should you say called?Explain carefully and completely, providing numerical evidence.
