Maggie bought 2 boxes of cupcakes for her daughters. she ate one cupcake herself and told her 3 daughters to share the remaining cupcakes equally. if there were c cupcakes in each box, what is the expression for the number of cupcakes each daughter gets?

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.
