However, if you're breastfeeding exclusively (and that means frequently, day and night), if your baby is younger than 6 months and if your period hasn't resumed, the so-called lactation amenorrhea method can be 98 percent effective in preventing pregnancy.
Then x has a expansion of decimal which terminates. 3) Let x =p/q be a rational number, such that the prime factorization of q is not of the form 25, where n, m are non-negative integers. Then, x has a expansion of decimal which is non-terminating repeating (recurring).
So far we have used two different equations for counting the elements in the union of two sets: . n(S âª M) = n(S) + n (M) and n(V âª P)= n(V) + n(P) â n(V â© P) Both equations are illustrations of the ADDITIONS PRINCIPLE (FOR COUNTING). Addition Principle (for counting) 1.) For any two sets of A and B, .
