A bag contains 6 white marbles and 4 black marbles. a marble is drawn without replacing the first one. what is the probability of drawing a white marble on the first draw, followed by a white marble on the second?

The probability of drawing a white marble on the first draw after following the second draw of white marble should be 0.33.

Given that

Now based on the above information

Put white marbles be

And, black marbles be

So,

= 10 - 4

= 6

Now pull two white marbles i.e.

Therefore we can conclude that The probability of drawing a white marble on the first draw after following the second draw of white marble should be 0.33.

6  = white marbles

4  = black marbles

10 =  total marbles

6/10 - Pulling white marbles

4/10 - Pulling black marbles

10 - 4 = 6

2/6 - Pulling two white marbles

I hope this helped!

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.
