If a p-value is lower than our significance level, we reject the null hypothesis. If not, we fail to reject the null hypothesis.

But after removing a King from the deck the probability of the 2nd card drawn is less likely to be a King (only 3 of the 51 cards left are Kings): P(B|A) = 3/51. And so: P(A and B) = P(A) x P(B|A) = (4/52) x (3/51) = 12/2652 = 1/221. So the chance of getting 2 Kings is 1 in 221, or about 0.5%

Mean: The "average" number; found by adding all data points and dividing by the number of data points. Example: The mean of 4 , 1 , and 7 is ( 4 + 1 + 7) / 3 = 12 / 3 = 4 . Median: The middle number; found by ordering all data points and picking out the one in the middle (or if there are two middle numbers, taking the mean of those two numbers).

After practicing filling truth table and gaining logic terminologies, the natural language intuition for "if p then q" is generally that p is a sufficient condition of q, while for "p only if q" q is a necessary condition for p. With these intuitions you can usually find answers with more ease.

In basic algebra a discrete variable is one that can only take on specific set of values. For example, if we were to say that X can only take on a whole value between 1 and 10, then X would be a discrete variable. On the other hand, a continuous variable is one that can take on an unlimited number of values.
