The probability of drawing a quarter from a bag of coins is 2/ 10 . What is the probability of drawing a coin that is not a quarter from the bag? 20% 40% 75% 80 pls help.

80%

Step-by-step explanation:

If the probability of drawing a quarter is 2/10, not drawing one would be 8/10, which is 80%.

step-by-step explanation:

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)
