Question

My brain is fried from this stuff :( Help!!!

A cake shop bakes a variety of brownies. The top-selling brownies are ones with toppings of chocolate chip, walnuts, or both. A customer enters the store. The probability that the customer will pick both toppings is 0.4. What is the probability that they will pick neither the chocolate chip nor the walnut toppings?

Answer 1

30% for plato :-)

Explanation:

Answer 2

Probabilities:
-Chocolate chip only: 0.2
- Walnut only: 0.1
- Both: 0.4
Total probability = 1
1 = 0.2 + 0.1 + 0.4 + x
x = 1 - 0.2 - 0.1 - 0.4= 0.3
Answer : 0.3 or 30%
