The probability that none of the shoes are black is 51.2%.

If 20% of the shoes are black, then 80% of the shoes are not black. To find the probability that three shoes are not black, we have to multiply 80% by itself 3 times.

0.8 x 0.8 x 0.8 = 0.512 = 51.2%

Part 1. Using the two functions listed below, insert numbers in place of the letters a, b, c, and d so that f(x) and g(x) are in
dem82 [27]

There is no b unfortunately

Find inverse of x+a

  • x+a=y

interchAnge

  • y+a=x
  • y=x-a

Inverse is

  • f^{-1}x=x-a

Now

  • x-a=cx-d
  • x-cx=a-d
  • x(1-c)=a-d
  • x=a-d/1-c

So

You can have any number according to this but

  • c must not be 1
  • a and d must not be equal .
  • All three should belongs to integers set

Note:-

As there is no b given in question (May be missed in typing) Part-2 's equation can't be executed and part 3 also
