The probability that the customer will pick neither the chocolate chip topping nor the walnut topping is 0.6.
Probability refers to the chance of occurrence of an event.
Let E be an event. Then, the probability of E = P(E)
=> P(E) = [tex]\frac{Number Of Favourable Outcomes Of Event E}{Total Number Of Outcomes}[/tex]
Given: The probability that the customer will take both toppings = 0.4
We know that the total probability of an event occurring = 1.
Thus, the probability that the customer will take neither the chocolate chip toppings nor the walnut toppings = 1 - 0.4 = 0.6
