10/16 = .625 Analysis: a and d will be odd if and only if both are odd. Therefor, ad will be odd 1/4 the time. The same goes for bc. It will be odd 1/4 off the time. ad-bc is even if and only if both ad and bc are either odd or even. It's easiest to solve it from here with a table: ad bc ad-bc prob even even even 3/4*3/4 = 9/16 even odd odd 3/4*1/4 = 3/16 odd even odd 1/4*3/4 = 3/16 odd odd even 1/4*1/4 = 1/16 So, ad-bc will be even 9/16+1/16 = 10/16 of the time.
