Answer: $1,700
Step-by-step explanation:
The expected winning bid is the weighted average of the 2 different bids.
Half of the bids are for $1,500 so weight of $1,500 is 0.5.
Half of the bids are for $1,900 so weight of $1,900 is 0.5.
Expected Winning bid = (1,500 * 0.5) + ( 1,900 * 0.5)
= 750 + 950
= $1,700
