Question

Spinner 1 is divided into 4 spaces. Spinner 2 is divided into two colors, red and blue. Write the sample space for each of the following experiments:

a. Spin spinner 1 once
b. Spin spinner 2 once
c. Spin spinner 1 once and then spin spinner 2 once
d. Spin spinner 2 once and then roll a normal die
e. Spin spinner 1 twice
f. Spin spinner 2 twice

Answer 1

a. S=[1,2,3,4]
b. S=[Blue, Red]
c. S=[1 Red, 1 Blue, 2 Red, 2 Blue, 3 Red, 3 Blue, 4 Red, 4 Blue}
d. S= [1Red, 1Blue, 2 Red, 2 Blue, 3 Red, 3 blue, 4 red, 4 blue, 5 red, 5 blue, 6 red, 6blue]
e. S=[ (1,1) (1,2) (1,3) (1,4) (2,1) (2,2) (2,3) (2,4) (3,1) (3,2) (3,3) (3,4) (4,1) (4,2) (4,3) (4,4)
f. S= [ (Red Blue) (Blue Red) (Red Red) (Blue Blue)

Can anyone confirm if this is correct?

Answer 2

the solutions all look correct. My only comment is that question (d) I would probably put the spinner results 1st then the die results... you have then the other way around.
