for the experiment of rolling an ordinary pair of
dice, find the probability that the sum will be even or a multiple
of 6. ( you may want to use a table showing the sum for each of the
36 equally likely outcomes.)
Consider a random experiment of rolling 2 dice. What is
probability of rolling a sum larger than 9? Select the best answer.
A. 0.5
B. 0.1667
C. 0.2333
D. None of the above
Find the probability that the sum is as stated when a pair of
dice is rolled. (Enter your answers as fractions.) (a) odd and less
than 5 (b) odd or less than 5
Find the probability that the sum is as stated when a pair of
dice is rolled. (Enter your answers as fractions.) (a) odd and
doubles (b) odd or doubles
A pair of dice is cast. What is the probability that the sum of
the two number landing uppermost is less than 5, if it is known
that the sum of the numbers falling uppermost is less than 7?
a) A pair of fair dice is thrown. What is the probability of
rolling a value between 8 and 11, inclusive? (Write your answer as
a decimal rounded to 3 decimal places.)
b) What is the probability of drawing a black face card when a
single card is randomly drawn from a standard deck of 52 cards?
(Write your answer as a decimal rounded to 3 decimal places.)
1.) In rolling a pair of dice, what is the probability of a
total of 4 or less?
2.) A blue die and a red die are tossed together. Find the
probability that the sum is less than 7, given that the blue die
shows a 3.
3.) A fair coin is tossed three times. Find the probability of
getting at least two tails, given that the first toss is tails.
Consider the experiment of rolling two dice and the following
events:
A: 'The sum of the dice is 8'
and B: 'The first die is an odd number' and
C: "The difference (absolute value) of the dice is
2"
Find (a) p(A and B) (HINT: You cannot
assume these are independent events.)
(b) p(A or
B)
(c) Are
A and B mutually exclusive events? Explain.
(d) Are A and B independent events?
Explain.
(e) Are B and C independent events?
Explain.
