A>70*9
a>360
a should be at least 361
Figure this out as though no digits are present. You can choose 8 of the 26 letters and that's it.
26^8 [you can allow repeating letters] = 2.088 * 10^11
The total number of ways that can be chosen with letters and digits intermixed = 36^8
The probability of getting no numbers is 26^8 / 36^8 or (26/36)^8 = 0.07402
So the probability that there were be at least one digit is
1 - 0.07402 = 0.92598
Bisector is simply a straight that divides the line (through which it's passing) into two equal halves. Or simply, it passes through the midpoint of any line. It may make any angle with the line through which it passes.
Perpendicular Bisector is also the same but the only difference is that it makes an angle of 90° with the line through which it passes or cuts.
I think it’s b... I don’t but i tried if it is wrong I’m sorry if it was right your welcome
