here are 55 black balls and 99 red balls in an urn. If 44 balls are drawn without replacement, what is the probability that exac
ElenaW [278]

Answer:

P=0.0899.

Step-by-step explanation:

We know that are 5 black balls and 9 red balls in an urn. If 4 balls are drawn without replacement. We calculate the probability that exactly 3 black balls are drawn.

Therefore, we have 14 balls in an urn.

We calculate the number of possible combinations:

C_4^{14}=\frac{14!}{4!(14-4)!}=1001\\

We calculate the number of favorable combinations:

C_3^5\cdot C^9_1=10\cdot 9=90

Therefore, the probability is:

P=90/1001

P=0.0899.

Natasha2012 [34]

Answer:

  • x² - 2x - 15 = 0

Step-by-step explanation:

<u>Roots:</u>

  • x₁ = -3, x₂ = 5

<u>The equation:</u>

  • (x - x₁)(x - x₂) = 0
  • (x - (-3))(x - 5) = 0
  • (x + 3)(x - 5) = 0
  • x² + 3x - 5x - 15 = 0
  • x² - 2x - 15 = 0
