Question

(1 point) Suppose the chance a player will win a single round of a certain gambling game is (supposedly) 25%, independently of other rounds. You play 100 rounds and win only 18 times. This is less than the expected value. Was it just bad luck

Answer 1

It was simply a case of bad luck.

Explanation:

The predictable win outcome from playing a round of a certain gambling game = 25%

If one plays 100 rounds, the predictable wins should be 25 (100 * 25%)

If the actual wins = 18, which is less than the predictable wins of 25, the actual result is less than the expected value or outcome by 7. This is simply a case of bad luck. Bad luck is defined as an unpredictable outcome that is unfortunate. It is when the predicted (expected) outcomes, 25 wins, are more than the unpredicted (actual observed) outcomes, 18 wins.
