<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%

Answer:
the square root of 105 lies between 10 and 11
Step-by-step explanation:
Which perfect squares "box" 105 in? 10^2 = 100 and 11^2 = 121.
The square roots of 100 and 121 are 10 and 11.
Thus, the square root of 105 lies between 10 and 11.
