Oscar sells a product on EBay for 100 days. The products sell for $25 on 35 days, $18 on 45 days, and do not sell at all on the remaining 20 days. Based on this 100-day history, the expected price is $16.85.
We have give that,
X1=$25 , f1 = 35 Days
X2=$ 18, f2=45 Days
X3= $ 0 ,f3= 20 Days
Thefore ,N = f1 +f2 +f3 = 100 Days
Therefore, Now expected Price will be
= = ( 25*35 + 18*45 + 0*20 ) / 100
= 1685 / 100
= $ 16.85
