Cedric has 4 pencils and blue pens and a black pen in his desk if he randomly draws two of them from the desk without replacement what is the probability he will draw the two pen?
This question has some missing information but the way you do this problem is to multiply fractions formed by probabilities. To draw two pens out of the drawer first take the ratio (fraction) of the number of pens over the total number of writing tools. Then, multiply that by one less on the top and the bottom. Lets say you have 4 pencils, 2 blues and 1 black. Seven total. 2/7*1/6=2/42 probability.
