What is the value of the z-score of the mean of a set of data? This question is so confusing to me haha.​

What is the value of x in the this question ?

Suppose i pick a jelly bean at random from a box containing one red and eleven blue ones. i record the color and put the jelly bean back in the box. if i do this three times, what is the probability of getting a blue jelly bean each time? (round your answer to three decimal places.)

Check all that apply. f is a function. f is a one-to-one function. c is a function. c is a one-to-one function.
