Dy / dx P (x) y = Q (x) where P (x) and Q (x) are functions of x If we multiply all terms in the differential equation given above by an unknown function u (x), the equation becomes u (x) dy / dx u (x) P (x) y = u (x) Q (x)Observe that according to Euler's totient formula, let a be any integer coprime to p, then (a, p) = 1 Then a^ (phi (p)) â ¡ 1 (mod p) Now since p is prime, all a in Z/PZ is coprime to p and phi (p) = (p1) Then (xy)^p = (xy) (xy)^ (p1) (mod p) â ¡ (xy) (1) (mod p)It seems that there's tendency to agree upon p (x)⇒∀xp (x) is the same as ∀x (p (x)⇒∀yp (y)), whereas ∀x (p (x)⇒∀yp (y)) is read as if p (x) is true for some x, then it is true for all x However I don't understand where's the quantifier SOME came from, since there no quantifier '∃' in '∀x (p (x)⇒∀yp (y))'

P(X= 129) = P(X= 129 and Y = 15) P(X= 129 and Y = 16) = 012 008 = 0 What is the probability distribution of X?Given random variables X, Y, {\displaystyle X,Y,\ldots }, that are defined on a probability space, the joint probability distribution for X, Y, {\displaystyle X,Y,\ldots } is a probability distribution that gives the probability that each of X, Y, {\displaystyle X,Y,\ldots } falls in any particular range or discrete set of values specified for that variable In the case of only two random variables, this is called a bivariate distribution, but the concept generalizes to anyFZ(z) = P(Z ≤ z) = P(X/Y ≤ z) = ˆ 0 if z < 0 P(Y ≥ (1/z)X) if z > 0, where we have used the fact that X and Y are both nonnegative (with probability 1), so multiplying both sides of the inequality by Y does not flip the inequality;
