16+25 = 41 which is an odd number and also a prime number
How many odd numbers are there from 16 to 30? Seven {7} odd numbers
There are 7 odd numbers between 16 and 30. To find this, you can subtract the largest odd number less than 30 (29) from the smallest odd number greater than 16 (17), then divide by 2 and add 1. So, (29-17)/2 + 1 = 7 odd numbers between 16 and 30.

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.
