Answer:
a. 4600
b. 6200
c. 6193
Step-by-step explanation:
Let 
the number of elements in A.
Remember, the number of elements in 
satisfies
Then,
a) If 
, and if 
Since 
So
b) Since the sets are pairwise disjoint
c) Since there are two elements in common to each pair of sets and one element in all three sets, then
Step-by-step explanation:
5x-12=13
5x -12 =13
+12=+12
<u>5x</u>= <u>25</u>
5 =. 5
x=5
There are total of 5 digits, of which we arrange 3 of them.
Therefore using permutations we can find total possible 3-number combinations.
5P3 = 5*4*3 = 60
To be greater than 600 means first digit must be 6. (1 possibility)
A number is even only if last digit is even, 2 or 4. (2 possibilities)
The 2nd digit then can only be 3,5, (2 or 4). (3 possibilities)
The total possible even 3-digit numbers greater than 600 is product of each digit's possibilities.
---> 1*3*2 = 6
Therefore probability is 6/60 = 1/10.
