Pat's Pizza made 21 cheese pizzas, 14 veggie pizzas, 23 pepperoni pizzas, and 14 sausage pizzas yesterday.
Sophie [7]
The probability of the next pizza not being cheese is 
P(not cheese) = 100 - P(cheese)

the probability of it being cheese is 21/(total)
Total = 21 + 14 + 23 + 14
Total = 72

So, P(cheese) = 21/72 x 100
which is roughly 29%

So P(not cheese) = 100 - 29 = 71%
