DropBoite Posted May 2, 2012 Report Share Posted May 2, 2012 (edited) Hey guys! In the picture attached I don't understand how question b was solved. Question b is: Sandra definitely knows the first correct statement but has to guess the second. What is the probability that she will answer both correctly? WOOPS Bad screenshot, okay the fraction covered by the dialog box is : 1/4 and it is the probability for a second correct. Sorry for the inconvenience! Thank you alll!! Bless you'll!
