Answer:

It's 2.6

Step-by-step explanation:

Someone else put that it's 2.06 but it is actually 2.6

Using the discrete distribution, it is found that the expected number of posts of the company each day is 2.6.

Distribution:

The discrete distribution is:

  • [tex]P(X = 0) = 0.05[/tex]
  • [tex]P(X = 1) = 0.1[/tex]
  • [tex]P(X = 2) = 0.35[/tex]
  • [tex]P(X = 3) = 0.25[/tex]
  • [tex]P(X = 4) = 0.2[/tex]
  • [tex]P(X = 5) = 0.05[/tex]

Expected value:

  • The expected value of a discrete distribution is given by the sum of each outcome multiplied by it's respective probability, hence:

[tex]E(X) = 0(0.05) + 1(0.1) + 2(0.35) + 3(0.25) + 4(0.2) + 5(0.05) = 2.6[/tex]

The expected number of posts of the company each day is 2.6.
