Explanation / Answer

The values which are negative are the amount the stock owners lost.Let X be the amount stock owners lost, let Y be the amount thatstock owners gained. Then, the cardinality of X = 4 => {-65, -60, -40, -20} And of Y = 7 => {0, 20, 40, 60, 80, 100, 110} Where the total number N of the stock owners is 11 => {-65, -60,-40, -20, 0, 20, 40, 60, 80, 100, 110} Therefore, the percentage of those stock owners who lost moneyis |X| / N = 4 / 11 ˜ 36.4%
