===>1. How would you use the expected value as one measure for consideration about when to discharge the patient?

x	P(x)	xP(x)
0	0.08	0
1	0.16	0.16
2	0.32	0.64
3	0.28	0.84
4	0.12	0.48
5	0.04	0.2
Sum	1	2.32

respond to this answer below Please

Expected Value

E(x)==xP(x)=0x0.08+1x0.16+2x0.32+3x0.28+4x0.12+5x0.04=2.32

Ex=xP(x)=0+0.16+0.64+0.84+0.48+0.20=2.32

During a 12-hour shift, the average post-operative patient will call the nurse 2.32 times.
