A set of 12 cards is numbered 1, 2, 3, ... 12. Suppose
you pick a card at random without looking. Find
the probability of each event. Write as a fraction in
simplest form.
5.
P(5)

56

step-by-step explanation:

14

step-by-step explanation:

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

3 is greater then both of those numbers
