Calculating binomial probability. 70 % of a certain species of tomato live after transplanting from pot to garden. Najib transplants 3 of these tomato plants. Assume that the plants live independently of each other. Let X = the number of tomato plants that live. So we are calculating 99% of 10% which is 0.10*0.99=0.099. This is the true positive rate (test positive and actually have the disease). Of the 10% of the population that have the disease 1% will have a negative test result. (test negative but actually have the disease). 1% of 10% is 0.10*0.01=0.001.

Mutually Exclusive Events. An experiment consists of drawing one card from a well shuffled deck of 52 cards. Consider the events E: the card is red, F: the card is a five, and G: the card is a spade.It is possible for a card to be both red and a five at the same time but it is not possible for a card to be both red and a spade at the same time. The general multiplication rule. For any two events, we can say that. P ( A and B) = P ( A) ⋅ P ( B | A) ‍. The vertical bar in P ( B A) ‍ means "given," so this could also be read as "the probability that B occurs given that A has occurred." Probability is traditionally considered one of the most difficult areas of mathematics, since probabilistic arguments often come up with apparently paradoxical or counterintuitive results. Examples include the Monty Hall paradox and the birthday problem.
