Maria defined the random variable X as the number that comes up when rolling a standard die. She then correctly constructed a bar graph of the probability distribution of X, with the values of X along the horizontal axis, and the vertical axis representing the probability of X, or P(X). Which statement is correct about Maria’s bar graph?

The bars are all same height, because values of X are all the same.

The bars are all different heights, because values of X are all different.

The bars are all the same height, because the values of P(X) are all same

(where theyre all the same?)
and thanks so much

princeharryyy · Answer

Yeah as there I same probability of getting a different no. In each case hence p(x) will be same in all cases. Hence the answer :)
