In designing a general service faelity, eapacity should be such that the target rate of sorvice utilization $(),$ in order to get the best general$-$purpose design, should be

A$.$between $0\mathrm{.}9(90\%)$ and $1\mathrm{.}0(100\%)$ so that the utilization of the system is ideal. B$.$less than $0\mathrm{.}6($or $60\%),$ so that your system would be within the zone of service with maximum possible utilization within that.

Cmore than $1\mathrm{.}0(100\%)$ so that the servers are fully utilized, even if the customers had to wait a little.

Dmore than $0\mathrm{.}6($or $60\%)$ so that your system would have a good utilization.

Eabout $0\mathrm{.}7(70\%)$ so that your system would be in the zone of service with maximum possible utilization within that.

$5.$ In a decision tree problem involving capacity planning, there was a random outcome node with three random outcomes $($A$,$B$,$ and C$)$ which followed a decision node. The probabilities for $A,B$ and $C$ are $P(A)=0\mathrm{.}4,P(B)=0\mathrm{.}6$ and $P(C)=0\mathrm{.}2.$ Payoff following $A,B$ and $C$ respectively are $$10000,$$$5000$ and $$2000.$ Expected value of that random autoome node is

A$.57400$

B$.$ $$7000$

C$.$ $$17000$

D$.$ Cannot be determined since there is something wrong with the data given.
