You have 6 books on your shelf. you notice that 3 of them have red covers, and 3 of them have blue covers.
if you choose 2 books from your shelf at random, what is the probability that 1 will have a red cover and 1 will have a blue cover?
enter your answer as a fraction in simplest form, using the / symbol, like this: 42/53

-60.75

step-by-step explanation:

just add the numbers then put the negative sign on it

step by step solution :

step   1   :

1.1     4 = 22

(4)3 = (22)3 = 26

equation at the end of step   1   :

  ((23) • 26)2

step   2   :

equation at the end of step   2   :

  (23 • 26)2

step   3   :

final result :

  218

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
