Answer with Step-by-step explanation:
a.
x is a real number
Therefore, the set={-1,1}
b.x is a positive integer less than 12
Therefore, the value of x are
1,2,3,4,5,6,7,8,9,10,11
Set={1,2,3,4,5,6,7,8,9,10,11}
c.x is a square of an integer and x<100
Therefore, the value of x can be
1,4,9,16,25,36,49,64,81
Set={1,4,9,16,25,36,49,64,81}
d.x is an integer such that
But x is an integer
and
are not integers.
Therefore, there is no integer element which satisfied
Set=Null set=
Answer:
The probability of getting white marble in the first try and red marble in the second try (without replacement) is
Step-by-step explanation:
Given: A bag contains 6 red marbles, 6 white marbles, and 4 blue marbles.
The total number of marbles in the bag = 6 + 6 + 4 = 16
Someone is pull a marble.
The probability of getting a white marble P(W)=
P(W) =
Then that marble kept it (with out replacement).
Now the total number of marbles in the bag = 6(red) + 5(white) + 4(blue) = 15
In the second try, the probability of getting a red marble P(R) =
These two events are dependent, because the out comes of the first event influences the outcome of the second event.
So, the probability that someone could pull a white marble from the bag, keep it, and then pull a red marble on the second try = P(W) *P(R)
=
Now we can multiply the fractions and simplify.
=
Here GCF of 36 and 240 is 12. So divide both the numerator and the denominator by 12, we get
=
So, the probability of getting white marble in the first try and red marble in the second try (without replacement) is
