According to the Harris Poll, 70 % of dog owners buy their dogs holiday presents. Suppose you select a random sample of 25 dog owners from among the population of 30 dog owners at the dog park. Let X be a random variable equal to the number of dog owners who buy their dogs holiday presents.

The concluding part is missing in the question and it says we should find the probability that 2 of the people selected cook meals for their dogs

P(x2) = 0.1857

Step-by-step explanation:

N = 30; since there are 30 people that own dogs

k = 21; since there are 70% of dog owners who buy gifts for their dogs

n = 25; since we randomly select 25 people among the dog owners

x = 2; since we randomly select 2 people who cook meals for their dogs

Therefore, for clarity sake the solution is in the attachment ;

And the probability is 0.1857
