Question

b) find the probability of randomly selectinga household that has at least one dog____ (round to three decimal places as needed)

c.) FInd the probability of randomly selecting a household that has between one and three dogs, inclusive._____(round to three decimal places as needed)

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 Households 0.678 0.198 0.076 0.024 0.017 0.007 4 (a) Find the probability of randomly selecting a household that has fewer than two dogs. (Round to three decimal places as needed.)

Explanation / Answer

a) P(Fewer than 2 dogs) = 0.678 + 0.198 = 0.876

b) P(At least one dog) = 1 - P(No Dog) = 1 - 0.678 = 0.322

c) P(Between 1 and 3 dogs) = 0.198 + 0.076 + 0.024 = 0.298
