Abag contains 11 orange cubes and 9 black cubes once a cube is picked it is not replaced what is the probability of choosing 2 black cubes

18/95

Step-by-step explanation:

At first, there are 20 cubes, 9 of which are black.  The probability that the first cube is black is P = 9/20.

After the first cube is selected, there are 19 cubes left, 8 of which are black.  The probability that the second cube is black is P = 8/19.

The total probability is:

P = (9/20) (8/19)

P = 18/95

  n=   0.0000 - 0.3750 i  

  n=   0.0000 + 0.3750 i

step-by-step explanation:

one of these should be correct

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
