    can you solve this ques… for me

    A society needs to provide sufficient private trunks between 2 switches to accomodate 90% of call attempts among callers during the busy hour.Assume that there will be 560 callers at random times during that hour, and that call duration averaages 3 minutes.callers are instructed to attempt to call using a trunk; if blocked callers will use a more expensive company-issued calling many trunks will be needed?

    Take your Erlang B calculator:

    offered traffic = 560
    blocking rate = 10%

    result : number of lines = xxxx

    that’s your number of trunks.
