Plz timed what is the range of the function represented by the table? a.{2, 4, 6, 8, 10} b.{2.5, 5.0, 7.5, 10.0, 12.5} c.{2, 2.5, 4, 5.0, 6, 7.5, 8, 10, 12.5} d.{0.0, 0.5}

The random variable x has probability density function f (x) = k(−x²+5x−4) 1 ≤ x ≤ 4 or =0 1 show that k = 2/9 find 2 e(x), 3 the mode of x, 4 the cumulative distribution function f(x) for all x. 5 evaluate p(x ≤ 2.5). 6 deduce the value of the median and comment on the shape of the distribution.
