So in this question we're told that x, our competitors bid, is uniform between 15 ,000 and 20 ,000.
00:12
So that's suppose that you bid 17 ,000.
00:15
What's the probability your bid will be accepted? so probability of accepted, given our bid is 17 ,000.
00:24
It's going to be the probability that x is less than 17 ,000, which is 17 minus 15 over 20 minus 15.
00:33
So that's two -fifths.
00:36
So that's the probability of being accepted given our bid is 17 ,000.
00:43
Part b, let's suppose you bid 18 ,000.
00:46
What's the probability of being accepted then? so the probability of being accepted, given we bid 18 ,000, is the probability that x is less than 18.
00:54
So that's 18 minus 15 over 20 minus 15, which is three -fifths.
00:59
So the probability of being accepted, given your bid is 18, is three -fifths.
01:08
What amount should you bid in order to maximize the probability that you get the property? so the probability of being accepted given a bid is going to be the bid minus 15 divided by 20 minus 15.
01:21
And we want to maximize this with respect to b.
01:25
So we can maximize this by setting b equals...
