80 times could Kaitlyn expect to pull out a blue chip.

Step-by-step explanation:

  • The total number of chips in the bag = 7 white+5 red+ 8 blue = 20 chips.
  • Probability (blue chip) = number of blue chips / total chips

P(blue) = 8/20

She does this 200 times.

P(blue) for 200 times = (8/20)[tex]\times[/tex]200 = 80.
