In a certain community, 35% of the families own a dog, and 20%
of the families that own a dog also own a cat. It is also known
that 32% of all the families own a cat.
What is the probability that a randomly selected family owns a
dog?
What is the conditional probability that a randomly selected family
doesn't own a dog given that it owns a cat?

3. In a certain community, 36% of all the families have a dog and 30% have a cat. Of those families with a dog, 22% also have a cat. Compute the probability that a randomly selected family (a) has both a dog and a cat; (b) has a dog GIVEN that it has a cat. Hint. Interpret 22% as conditional probability.

you know what household owns cat what is probabiliy that also owns dog letter A represents cat ownership b dog ownership suppose 35 percent households in a pop 30 percent own dogs and 15 percent own both a cat and dog-suppose you know a household owns a cat what is probability they own a dog
In a town, 30% of the households own a dog, 20% own a cat, and 60% own neither a dog nor a cat. If we select a household at random, what is the chance that they own both a dog and a cat? please show all steps and also mention your reasoning in details.
26. DISTRIBUTION OF FAMILIES BY SIZE The Public Housing Authority in a certain community conducted a survey of 1000 families to determine the distribution of families by size. The results follow: Family Size 4 Frequency of Occurrence 350 200245 125 66 104 a. Find the probability distribution of the random vari- able X, where X denotes the number of people in a randomly chosen family. b. Draw the histogram corresponding to the probability distribution found in part (a). e. Find...
