When a customer places an order at Derin's bakery, there is an 85%85\%85%85, percent probability that the order will include some kind of dessert. One day, 7777 customers place orders at Derin's bakery.
Assuming that each order is equally likely to include dessert, what is the probability that at least one order will not include dessert?
Round your answer to the nearest hundredth.
P(at least one without dessert)=P(\text{at least one without dessert})=P(at least one without dessert)

If you add 5x to the x then it will equal 4x. Then the equation would be x^2+4x+4 which equals to (x+2)^2 when factored. (x+2)(x+2)=x^2+2x+2x+4=x^2+4x+4.

Hope this helped! :)
