True or false. There are some parallelograms that are rectangles.
RideAnS [48]

True, because a parallelogram is a four-sided rectangular figure with opposite sides parallel.  This is a way to describe a rectangle as well.  The only difference is that rectangles must have 90 degree angles, but it is possible for a parallelogram to have 90 degree angles as well.  This also means that all rectangles are technically parallelograms as well.

David Barnes and his fiancée Valerie Shah are visiting Hawaii. At the Hawaiian Cultural Center in Honolulu, they are told that
balandron [24]

Using the hypergeometric distribution, it is found that there is a 0.0065 = 0.65% probability that both David and Valerie get picked for the Tahitian dance lesson.

The people are chosen without replacement from the sample, hence the <em>hypergeometric distribution </em>is used to solve this question.

<h3>What is the hypergeometric distribution formula?</h3>

The formula is:

P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}

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

The parameters are:

  • x is the number of successes.
  • N is the size of the population.
  • n is the size of the sample.
  • k is the total number of desired outcomes.

In this problem:

  • There is a total of 18 people, hence N = 18.
  • 2 people will be chosen, hence n = 2.
  • David and Valerie corresponds to 2 people, hence k = 2.

The probability that both get picked is P(X = 2), hence:

P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}

P(X = 2) = h(2,18,2,2) = \frac{C_{2,2}C_{16,0}}{C_{18,2}} = 0.0065

0.0065 = 0.65% probability that both David and Valerie get picked for the Tahitian dance lesson.
