How likely is it to get pregnant after ovulation?

How long after?: This depends on how long after. Having intercourse a few hours after ovulation creates a strong chance of getting pregnant,up to 33% according to this website: http://yourfertility.org.au/for-women/timing-and-conception I'm skeptical it's as high as 33% but it is fairly high. However,by 24 hours after ovulation the chances of conceiving drop to zero until about 5 days prior to your next ovulation.
