PLEASE help! Probability! - A shoebox holds same-size disks. There are 5 red, 6 white, and 7 blue disks. You pick out a disk, record its color, and return it to the box. If you repeat this process 250 times, how many times can you expect to pick either a red or white disk?

    5 + 6 + 7 = 18 P = 250([6 + 7] / 18) P = 250(13 / 18) That's all I remember sorry :)
