Step 1

Given that 17% of the people own dogs, So 83% of people don't own dogs. Therefore, events are mutually exclusive.

P(Both the people own dogs)=P(first person own dogs) × P(second person own dogs)

Step 2

Therefore, probability can be calculated as: P(Both the people own dogs)=0.17 × 0.17 P(Both the people own dogs)=0.0289 Round to three decimals. P(Both the people own dogs)=0.029

Answer: 0.029

According to a study by Dr. John McDougall of his live-in weight loss program at St. Helena Hospital, the people who follow his program lose between 6 and 15 pounds a month until they approach trim body weight. Let's suppose that the weight loss is uniformly distributed. We are interested in the weight loss of a randomly selected individual following the program for one month. Give the distribution of X. Enter an exact number as an integer, fraction, or decimal.f(x)= where X.μ=σ=. Find the probability that the individual lost more than 8 pounds in a month.Suppose it is known that the individual lost more than 9 pounds in a month. Find the probability that he lost less than 13 pounds in the month.
