Answer:

Depends

Step-by-step explanation:

Well first to get to fraction multiply 3/4 by two = so there is 6 /8 of a cup of sugar for every 1/8 of butter so  8X6 = 48 so for every full cup like 8/8 there would be 48/8 cups of sugar or 6 full cups

Some parts of California are particularly earthquake-prone. Suppose that in one metropolitan area, 32% of all homeowners are ins
Bumek [7]

Answer:

P(X = 0) = 0.2138

P(X = 1) = 0.4025

P(X = 2) = 0.2841

P(X = 3) = 0.0891

P(X = 4) = 0.0105

Step-by-step explanation:

For each homeowner, there are only two possible outcomes. Either they have invested in earthquake insurance, or they have not. The probability of a home owner having invested in earthquake insurance is independent from other homeowners. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

32% of all homeowners are insured against earthquake damage.

This means that p = 0.32

Four homeowners are to be selected at random.

This means that n = 4

Find the probability distribution of X.

This is the probability of each outcome

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 0) = C_{4,0}.(0.32)^{0}.(0.68)^{4} = 0.2138

P(X = 1) = C_{4,1}.(0.32)^{1}.(0.68)^{3} = 0.4025

P(X = 2) = C_{4,2}.(0.32)^{2}.(0.68)^{2} = 0.2841

P(X = 3) = C_{4,3}.(0.32)^{3}.(0.68)^{1} = 0.0891

P(X = 4) = C_{4,4}.(0.32)^{4}.(0.68)^{0} = 0.0105
