FIRST ASSIGNMENT: MATH 10: WORKPLACE
8. A bag contains 5 red, 4 blue, 3 green and 2 black balls, and a single ball is selected. What is the probability
of selecting:
a. blue ball
1 mark
b. not a red or blue ball
1 mark
c. black or blue
1 mark
9. The Stair Game
The game starts on the fifth step of a staircase. Each player's turn consists of flipping two coins and moving up
or down according to the following rules:
If no heads appear on the player's two coins, the player does not move. If one head appears, the player moves
up one stair. If two heads appear, the player moves down one stair.
Calculate the following theoretic probabilities. (You may want to construct a tree diagram.)
a. Find P (no move) =
1 mark
b. Find P (up one) =
1 mark
c. Find P (down one) =
1 mark
10. What is the difference between experimental and theoretical probability?

step-by-step explanation:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.

step-by-step explanation:

given that megan owns a clothing boutique.

the profits of 2010, 11, are recorded and shown as follows:

years since     2010 0     1     2     3       4       5

profits made in 1000's   39       84     111     120   111     84

we find that profit gradually increases form 2010 to 2013 upto 120,   then starts decreasing.

the profits for 2012 and 2014 are the same while that of 2011 and 2015 are also the same.

this shows that there is symmetry about the line profit = 120000

hence answer is:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.
