According to the manufacturer of the candy Skittles, 20% of the candy produced are red. If we take a random sample of 100 bags o
WITCHER [35]

Answer:

0.15651

Step-by-step explanation:

This can be approximated using a Poisson distribution formula.

The Poisson distribution formula is given by

P(X = x) = (e^-λ)(λˣ)/x!

P(X ≤ x) = Σ (e^-λ)(λˣ)/x! (Summation From 0 to x)

where λ = mean of distribution = 20 red bags of skittles (20% of 100 bags of skittles means 20 red bags of skittles)

x = variable whose probability is required = less than 16 red bags of skittles

P(X < x) = Σ (e^-λ)(λˣ)/x! (Summation From 0 to (x-1))

P(X < 16) = Σ (e^-λ)(λˣ)/x! (Summation From x=0 to x=15)

P(X < 16) = P(X=0) + P(X=1) + P(X=2) +......+ P(X=15)

Solving this,

P(X < 16) = 0.15651

Semenov [28]

If a advertised sofa is $200 but the more costly sofa is $375, the average cost of such a sofa will be $200 is $243.75.

<h3>Define the term average of the number?</h3>
  • An averaging is a single number calculated as the average of a set of numbers,.
  • Typically calculated as the sum of a numbers divided by the total number of numbers in the set (the arithmetic mean).

You're planning to purchase a sofa from a furniture store that is having a sale on them.

Let x represent the sofa's price.

Advertised sofa's cost = $200

Expensive sofa's cost = $375

The advertisers are aware that when customers arrive at the store, one out of three switch to an expensive sofa that the one shown in the sale advertisement.

Average cost = 375 x 1/4 + 200 x 3/4

E(x) = 375 x 1/4 + 200 x 3/4

E(x) = 93.75 + 150

E(x) = 243.75

Thus, if a advertised sofa is $200 but the more costly sofa is $375, the average cost of such a sofa will be $200 is $243.75.
