<u>44%</u>
Sample space is 36C4
Now, we want to know all of the combinations that have 1 digit in it.
So, we can have one here:
1XXX
X1XX
XX1X
XXX1
But we have 10 different digits to choose from. So, we need to introduce the combination term, nCr, where n is a list of all digits and r is how many we want.
Since we only want one, we will need 10C1 for the number of digits. But we need to choose three lowercases, so it becomes 10C1 × 26C3
Since it's a probability question, we need to divide that by our sample space, 36C4, and our percentage becomes 44%

y=23
hope this helps!!
The solution is as follows:
Set up the proportion:
70% - 98
90% - x
70% / 90% = 98 / x
7 / 9 = 98 /x
(7 / 9) x = 98
x = 98 x 9/7
x = 14 x 9
x = 126
The answer is <span>D. 126.
I hope my answer has come to your help. God bless and have a nice day ahead!</span>
