Rework problem 7 from section 3.4 of your text, involving the selection of a colored ball from one of three bowls. Assume that y
allochka39001 [22]

Answer:

  • Question (1): 1/2 = 0.5

  • Question (2): 1/6 ≈ 0. 17

Explanation:

<u>1. Arrange the information of the balls contained in the bowls in a table:</u>

                       Bowl X      Bowl Y       Bowl Z     Total

Red balls              2               2                1               5

White balls           2                1                3              6

Blue balls             3                1                2              6

                           ==============================

Totals                     7                4              6             17  

<u>2. To answer each question use the basic definition of probabilities</u>

  • Probability = # of favorable events / # of possible events

<u>3. Question (1) If the ball is blue, what is the probability that it was drawn from bowl X? </u>

<u />

  • Number of total blue balls: 6
  • Number of blue balls in the bowl X: 3
  • Probability that a ball that is blue was drawn from the bowl X: P (b/X)

       P (b/X) = number of blue balls in the bowl X / total number of blue balls = 3 / 6 = 1/2 = 0.5

       

<u>4. Question (2) If the ball is either blue or white, what is the probability that it was drawn from bowl Y?</u>

  • Number of total blue and white balls: 6 + 6 = 12
  • Number of blue balls and white balls in the bowl Y: 1 + 1 = 2
  • Probability that a ball that is either blue or white was drawn from the bowl Y: P (b or w / Y)

       P (b or w /Y) = number of blue balls and white balls in the bowl Y / total number of blue balls and white balls = 2 / 12 = 1/6 ≈ 0.17

find point p that divides segment AB into a 2:3 ratio. The point should be closer to A. A(-3,1) and B(3,5)
Mademuasel [1]
First, work out how much you need to add to A's x and y coordinates in order to get to point B from point A.

So (using Ax to mean x-coordinate of A, Ay the y-coordinate of A, etc):
x-difference = Bx - Ax = 3 - (-3) = 3 + 3 = 6
y-difference = By - Ay = 5 - 1 = 4

Now, if the point divides the segment AB in the ratio 2:3, then it is 2/(2+3) of the way along the line AB.

i.e. it is 2/5 of the way along the line AB.

We therefore need to add 2/5 of the x- and y-differences to point A to get point p:
px = Ax + (2/5)*(x-difference) = -3 + (2/5)*6 = -3 + 12/5 = -15/5 + 12/5 = -3/5 = -0.6
py = Ay + (2/5)*(y-difference) = 1 + (2/5)*4 = 1 + 8/5 = 5/5 + 8/5 = 13/5 = 2.6

Therefore coordinates of p are (-0.6, 2.6)
