Q2. Two fair dice are tossed and recorded
(a) What is the probability that the sum of the two dice is at most
10?
(b) Given that the sum is an even number, what is the
probability that the sum of two dice is 6 or 10?
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
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.)
a. Two dice are rolled; find the probability that the sum of the
two numbers is 7.
b. If one card is drawn from a standard deck, find the
probability of getting a spade card or a Queen.
c. A couple has 3 children, find the probability that exactly
one are girls.
Three symmetrical and homogeneous dice are tossed
simultaneously. Find the probability of event A: the total number
of dots appears at 10 if we know that at least one dice has upper
face 3 dots. (Sorry I'm not good at English)
(FIXED) .Three symmetrical and homogeneous dice are tossed
simultaneously. Find the probability of event A: the total number
of dots appears at 10, given event B is at least one dice has upper
face 3 dots. (the result of lesson is p(A|B) = p(AB)/p(B) =
(15/6^3)/(91/6^3))
