Dina has a number cube that she uses for a game. the number cube has the shape of a triangular pyramid, with 4 faces numbered 1 through 4. dina rolls the number cube 100 times and records the results. she calculates the relative frequency of each outcome. outcome 1 2 3 4 relative frequency 0.23 0.24 0.26 0.27 which statements about dina's experiment are true?
select each correct answer.
a the relative frequencies in the table are reasonably close.
b the theoretical probability of rolling an even number is 0.51.
c the relative frequency of rolling an even number is 0.51.

(fog)(x) if f(x)=x^2- 4 and g(x)=x^2 + 2 x, f(g(x))= f(x^2+2x) (x^2+2x)^2-4 (x^2+2x)(x^2+2x)-4 (x^4+2x^3+5x+4x^2)-4 x^4+2x^3+4x^2+5x-4 what am i doing wrong
