Color Sequence Experiment
Suppose that we have a special box -
each time we press a button on the box, it prints out a sequence of colors, in order
- it prints four colors at a time. Suppose the box follows the following
Probabilities for each Color Sequence:
Color Sequence |
Probability CS
Prints Out |
BBBB |
.10 = 10% |
BGGB |
.25 = 25% |
RGGR |
.05 = 05% |
YYYY |
.30 = 30% |
BYRG |
.15 = 15% |
RYYB |
.15 = 15% |
Total |
1.00 = 100% |
Let's
define the experiment: We push the button, and then the box prints out exactly
one(1) of the above listed color sequences. We then note the resulting(printed
out) color sequence. Let's discuss the simple(or basic) events. The simple
events are the color sequences. The probabilities for each color sequence are
given in the table.
Suppose
we define the event E={Blue(B) is printed in
the 2nd or 3rd slot}. Compute the probability for event
E, and show me how you did it. Also, interpret the probability for event E.
Suppose
we define the event F={Yellow(Y) is
printed at least once in the sequence}. Compute the probability for event F,
and show me how you did it. Also, interpret the probability for event F.
Suppose
we define the event G={Green(G) is printed in
the 2nd slot}. Compute the probability for event G, and show me how
you did it. Also, interpret the probability for event G.
Suppose
we define the event H={Red(R) is not the 1st
color}. Compute the probability for the event H, and use the Complementary
Rule. Also, interpret the probability for H.
Suppose
we define the event I={Blue(B) is not the 4th
color}. Compute the probability for the event I, and use the Complementary
Rule. Also, interpret the probability for I.
