A person eating at a cafeteria must choose 4 of the 13 vegetables on offer. calculate the number of elements in the sample space
Serggg [28]

A person eating at a cafeteria must choose 4 of the 13 vegetables on offer. calculate the number of elements in the sample space for this experiment.

Answer: The number of elements in the sample space for this experiment can be found using the combination formula because the order does not matter here.

Therefore, the number of elements in the sample space for this experiment is:

13C4=\frac{13!}{(13-4)!4!}

              =\frac{13!}{9! \times 4!}

              =\frac{6227020800}{8709120}

              =715

Therefore, the number of elements in the sample space for this experiment is 715.

For which situations is it appropriate to use a sample? Select three options.
maw [93]

Answer:

B C D

Step-by-step explanation:

We use samples when using an entire population is not feasible.

It is not reasonable to ask every pick-up truck driver what they want their next purchase to be; there are too many owners of pick-up trucks.  This means we should use a sample.

Many people drive a highway that connects two large cities.  It is not reasonable to survey every person that drives it, so we should use a sample.

On a busy road, we may have many pedestrians; this means we should use a sample instead of the entire population.
