Answer:
a) 0.00001
b) 0.001
Step-by-step explanation:
Given numbers,
0, 1, 2, 3, 4, 5, 6, 7, 8, 9
a) If by these numbers we have to make six digit number,
So, the total ways of arranging 6 digit number =
Now, if all six digit in the number are same,
Then the possible ways = 10 ( eg : 000000, 111111, 222222, 333333, 444444... etc ),
Hence, the probability that all six digits are the same
b) The ways that five or more of the digits of the same = exactly 5 digits are same + Exactly 6 digits are same
∵ The ways that 5 digits are same = 10 × 9 = 90 (i.e. 111110, 111112, 111113,.....9 times, 222220, 222221,.....9 times .... etc..)
So, the number of ways that 5 or more than 5 digits are same = 90 + 10 = 100
Hence, the probability that five or more of the digits of the same

Answer:
Please check the explanation.
Step-by-step explanation:
Given the equation
All we need is to find any random value of 'x' and then solve for 'y'.
For example, putting x=2
Thus, (2, 17) is one of the many ordered pairs solutions of the equation.
Similarly, putting x=3
Thus, (3, 21) is one of the many ordered pairs solutions of the equation.
