A bag contains 8 black beads and 4 white beads. If 2 beads are drawn at random, what is the probability that both beads are blac
maria [59]

Answer:

14/33

Step-by-step explanation:

The total amount of beads is 8+4 = 12.  8 of these are black beads, so that is what we want, so 8/12 or 2/3.  For the second one, one black bead is already taken so 8-1 = 7 are left and for the total 12 - 1 = 11 are left, so 7/11.  Multiply this by 2/3 and we get 14/33.

No the value of functions are not same .

What is function in math?

  • A quantitative expression, rule, or law that describes the link between an independent variable and a dependent variable (the dependent variable).
  • In mathematics, functions occur widespread, and they are essential for defining physical links in the sciences.
  • A function is a type of rule that generates one output for a single output.
  • This is represented by the equation y=x2. Any inputs for x result in an output for y. Given that x is the input value, we would state that y is a result of x.
