We select four distinct integers from the set {1,2,…,20} , uniformly at random (all quadruples of distinct integers are equally likely), and arrange them in ascending order. find the probability that after ordering them, the second number is equal to 7 .

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3

answer: you need the equation in the question so i can answer it

step-by-step explanation:

what? that isnt a question
