Nana76 [90]

Answer:

  • 17 1/3 or 17.33

Step-by-step explanation:

<u>Mean of four numbers a, b, c, and d is 8:</u>

  • (a + b + c + d)/4 = 8  
  • ⇒ a + b + c + d = 32

<u>Mean of seven numbers x, y, z, a, b, c and d is 12:</u>

  • (x + y + z + a + b + c + d)/7 = 12

<u>Substitute the sum of 4 numbers:</u>

  • x + y + z + 32 = 7*12
  • x + y + z = 84 - 32
  • x + y + z = 52

<u>Mean of x, y and z is:</u>

  • 52/3 = 17 1/3 or 17.33

Goryan [66]

Answer:

Step-by-step explanation:

The probability of not drawn a red ball is 3/6. The probability of not drawn a green ball is 4/6, and the probability of not drawn a yellow ball is 5/6. So, the probability of not drawn at least one color is the multiplication of the probabilities of each color, so (3/6)*(5/6)*(4/6) = 0.2777.
