Q:

A box contains 3 red, 2 white, and 5 blue beads, each of which is a solid color. miguel will randomly remove 1 bead from the box, record the color of the bead, and return the bead to the box. miguel will complete this process 50 times. how many times should miguel expect to record a bead color that is not white?

Accepted Solution

A:
For every 10 it is 8/10 chance that it is NOT white.

So, if drawn 50 times...

8/10 x 50/1 =
8 x 50 = 400
10 x 1 = 10
400 / 10 = 40

40/50

He should expect to record a bead that is not white 40 times.

I haven’t done probability in awhile so I’m sorry if this is wrong :( Hopefully it’s right
