Each user on a computer system has a password, which is six to eight characters long, where each character is an uppercase letter or a digit. Each password must contain at least one digit.how many possible passwords are there? I understand sum rule will be applied adding ... how we will ensure password will contain one digit? in rosen solution P6 = 36^6  26^6 why they did like this?

Kenneth Rosen Edition 6th Exercise 1.3 Example 23 (Page No. 42)
Express the statement Every student in this class has studied calculus using predicates and quantifiers. Solution: First, we rewrite the statement so that we can clearly identify the appropriate quantifiers to use. Doing so, we obtain: For every ... its C(x) not C(calculus). So, the value is not given as input there. Then why now?

Self Doubt
Let < G, * > be a finite group and let H1 and H2 be it's sub group as per lagrange theorem we know order of sub group divides order of group, my doubt is, is it possible that we can have multiple subgroup of same cardinality for a particular group ? $\left  H1 \right =\left  H2 \right $
