Suppose that a student is randomly selected from a large high school. The probability that the student is a senior is 0.22. The
lawyer [12517]

Answer: La probabilidad que necesitamos es 0.16.

Step-by-step explanation:

Se nos proporciona que

La probabilidad de que el estudiante sea un senior = 0.22

La probabilidad de que el estudiante tenga una licencia de conducir = 0.30

La probabilidad de que el estudiante sea un senior o tenga una licencia de conducir = 0.36

Buscamos la probabilidad de que el estudiante sea un senior y tenga licencia de conducir.

Según la pregunta,

P(S\cap D)=P(S)+P(D)-P(S\cup D)\\\\P(S\cap D)=0.22+0.30-0.36\\\\P(S\cap D)=0.16

Por lo tanto, la probabilidad que necesitamos es 0.16.

The marked price of an article is Rs.2080. After allowing d% discount and levying
AnnZ [12381]

Answer:

13%

Detailed breakdown:

Information provided:

  • MP = 2080
  • Discount = d%
  • VAT = (d-2)%
  • Cost = 1997.84

Applying the discount:

  • 2080 - d% = 2080*(1 - 0.01d)

Including VAT:

  • 2080*(1 - 0.01d) + (d - 2)%
  • 2080*(1 - 0.01d) * (1 + (d -2)/100)
  • 2080*(1 - 0.01d) * (0.98 + 0.01d) = 1997.84
  • (1 - 0.01d)(0.98 + 0.01d) = 1997.84/2080
  • 0.98 + 0.01d - 0.0098d - 0.0001d² = 0.9605
  • - 0.0001d² + 0.0002d + 0.98- 0.9605 = 0
  • 0.0001d²- 0.0002d - 0.0195 = 0
  • d² - 2d + 195 = 0

Solving this quadratic equation yields:

  • d = 15

Therefore

  • VAT rate = 15 - 2 = 13%
