Hey there, welcome to numerade.
00:03
We are asked to find the probability that the pizza that's chosen at random is a cheese pizza eaten at work.
00:13
So what we know here is that we sold 23 cheese pizzas and 19 pizzas with one more toppings.
00:21
So therefore our sample size here, 23 plus 19.
00:27
So that's basically 33 plus 9, equaling 42 pizzas in total.
00:34
So our formula that we're going to work with here is the probability of getting a cheese pizza given that it was at work, eating at work.
00:55
So in order to find this probability here, this will basically equal the probability of a cheese pizza and work.
01:21
So we have divided by the probability of work.
01:33
All right.
01:36
So knowing this here, we have the probability of cheese and work, which is basically given to us as 12...
