Question

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 Households 0.691 0198 0.071 00210 015 0004 (a) Find the probability of randomly selecting a household that has fewer than two dogs Dogs 0 Round to three decimal places as needed) (b) ind the probability f randomly selecting a household that has at least one dog (Round to three decimal places as needed) () Find the probability of randomly selecting a household that has between one and three dogs, inclusive (Round to tiree decimal places as needed Enter your answer in each of the answer boxes 10/18 17

Explanation / Answer

a) P(X<2) =P(X=0)+P(X=1) =0.691+0.198 =0.889

b) P(X>=1) =1-P(X=0) =1-0.691 =0.309

c)P(1<=X<=3) =0.198+0.071+0.021 =0.290
