Four numbers are selected without replacement from
{1,2,3,4,5,6,7} to form a 4-digit number. What is the probability
that the number is greater than 6543?
Four numbers are selected without replacement from the set of
1,2,3,4,5,6,7 to form a 4 digit number. What is the probability
that the number is greater than 5432?
Three digits are randomly chosen from {1,2,3,4,5,6,7} without
replacement.
a) What is the probability the number formed is 123 or 567?
b) What is the probability the number formed has first digit
1?
c) What is the probability the number formed by the three digits
is greater than 520?
Three Digits from {1,2,3,4,5,6,7} are chosen and arranged in a
row without replacement.
Determine the number of different outcomes we could obtain
Find the probability of each event:
The digit 1 appears
All digits are even
At least one digit is even
The number is divisible by 5
if 4 cards are randomly selected without replacement from a deck
of cards, what is the probability of getting at least one ace (
exact reduced fraction or decimal or round to 3 significant
digits)?
Two
numbers are randomly selected without replacement from the
set{1,2,3,4,5}.Find the probability that:
a)both numbers are odd
b)both numbers are prime
A committee will be formed with 4 managers and 3 engineers
selected randomly without replacement from 11 managers and 16
engineers.
What is the conditional probability that engineer Al is on the
committee given that engineer Jane is on the committee?
Round your answer to three decimal places (e.g. 98.765).
Would the answer be ((3/16)x(2/15))/(3/16) ---> (2/15)
----> .1333333
From shuffled deck of cards, 4 cards are randomly selected
without replacement from shuffled deck of 52 cards. What is the
probability to get at least one ace?
1) 4 ballpoint pens are selected without replacement
at random from a box that contains 2 blue pens, 3 red pens, and 5
green pens.
If X is the number of blue pens selected and Y is the number of red
pens selected
a. Write the “joint probability distribution” of x and
y.
b. Find P[(X, Y ) ∈ A], where A is the region
{(x, y)|x + y ≤ 2}.
c. Show that the column and row totals of...
From the digits 0,1,2,3,5,7,8, and 9 , selected of them at random
and from a four-digit number, none of these digits appears more
than once in each number.
(a) Find the probability that the number formed is even.
(b) Find the probability that the number formed is divisible
by 3.
A three-digit number is formed from nine numbers (1, 2, 3, 4, 5,
6, 7, 8 & 9). No number can be repeated. How many different
three-digit numbers are possible if 1 and 2 will not be chosen
together?
Select one:
a. 462
b. 336
c. 672
d. 210
