What is p (not 3) ?

You roll a fair 6-sided die

P(not3)=5/6=.83

Step-by-step explanation:

Find probability of a die that didn’t have a 3 means that it could have a 1,2,4,5,6. This is 5out of 6.

5/6=.83

0.83

Step-by-step explanation:

There are six sides of a dice and you are trying to find the probabilty of rolling anything other then a three. That leaves you with 5 out of 6 sides that you can roll. Fraction is 5/6. 5/6 as a decimal is 0.83

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
