The chance of picking a jack at random from a pack of cards is 4/52. If it is, the chance of getting another jack is 3/52, if not, it is 4/51. Hence the probability of this second one is dependent on the first. Bayes theorem gives the probability that given the second card is an ace, the first card is also.<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/7648735277566931831-5874658638164243095?l=senior-chief.blogspot.com' alt='' /></div>Master Chiefhttp://www.blogger.com/profile/04578267304264231744noreply@blogger.com0tag:blogger.com,1999:blog-7648735277566931831.post-41600145562752233372008-06-12T20:28:00.000+08:002008-06-12T20:32:34.026+08:00To divide a fraction by a fraction, you simply change the symbol to a multiplication symbol and flip the second fraction.<br /><br />Therefore to divide a half by a half, which looks like this:<br />1/2 divided by 1/2<br />flip it so you get<br />1/2 x 2/1 which is clearly 2 / 2 which is 1.<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/7648735277566931831-4160014556275223337?l=senior-chief.blogspot.com' alt='' /></div>Master Chiefhttp://www.blogger.com/profile/04578267304264231744noreply@blogger.com0
