(1). A number is randomly selected from {80, 81, 82, 83, 84, 85, 86}. A is represented by the event that the number picked is less than 84. What is the probability of the complement of event A? Express your answer in a simplified fraction.
(2) A bouquet of flowers has 3 pink roses, 5 red roses, and 4
yellow roses. A represents the event that a randomly
selected flower is a pink rose. What is the probability of
the complement of event A? Express your answer as a
simplified fraction.
(3) A car license plate is made up of 7 letters or numbers, where
the numbers are whole numbers 0 – 9. Suppose that a
license plate is randomly generated, one character at a time.
What is the probability that the first character is a number?
Express your answer as a decimal to the nearest hundredth.
(4) Two number cubes are rolled. What is the probability,
expressed as a simplified fraction, that the first lands on 6
and the second lands on an odd number?
(5) Vicki would like to estimate the probability of tails
coming up fewer than 2 times in 3 coin flips. To do
this, she has a computer randomly select 0 or 1
three times, with 0 representing heads and 1
representing tails. The results of 15 trials are
shown in the table. What is Vicki’s estimated
probability, based on the simulation as a fraction?
