Use the probability distribution to find probabilities in parts​ (a) through​ (c).

The probability distribution of number of dogs per household in a small town


Dogs 0 1 2 3 4 5

 

Households 0.684 0.199 0.025 0.012 0.008


​(a) Find the probability of randomly selecting a household that has fewer than two dogs.



0.883  ​(Round to three decimal places as​ needed.)

​(b) Find the probability of randomly selecting a household that has at least one dog.


0.316 ​ (Round to three decimal places as​ needed.)

​(c) Find the probability of randomly selecting a household that has between one and three​ dogs, inclusive.


0.296 ​ (Round to three decimal places as​ needed.)



I got A and C right but cannot figure out how to get the answer for B. After getting it wrong 3 times it told me that 0.316 was the correct answer.
