Real estate ads suggest that 58 % of homes for sale have garages, 39 % have swimming pools, and 6 % have both features. what is the probability that a home for sale has a) a pool or a garage? b) neither a pool nor a garage? c) a pool but no garage?

(a) 0.91

               (b) 0.09

               (c) 0.33

Step-by-step explanation:

Let probability of having a garage be P(G) = 0.58

And probability of having a swimming pool P(p) = 0.39

Probability of having both P(G and p) = 0.06

(a) P( pool or garage) = P(p) + P(G) - P(P and G)

Using the general addition rule add the probability of a house with a pool plus the probability of a house with a garage and subtract the probability of a house with both a garage and a pool.

                                    = 0.58 + 0.39 -0.06

                                   = 0.91

(b) P( neither pool nor garage) = 1 - P(pool or garage)

Probability of not having a pool nor a garage can be found by subtracting the probability of having a pool or a garage.

                                                   = 1 - 0.91

                                                    = 0.09

(c) P(pool and no garage) = P(p) - P(p and G)

Probability of a house with a pool but no garage can be found by subtracting the probability of having both a pool and a garage from the one of having only a pool.

                                          = 0.39 - 0.06

                                          = 0.33

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
