What is probability?

Probability is a fairly new topic that was recently reintroduced into Standard Grade maths. The best way to describe this is to give a few examples. Probability is defined as (number of favourable outcomes) / ( total number of outcomes) Example 1 A pack of cards is shuffled and then a card is selected at random. What is the probability that a red card is drawn from the pack. In a pack of cards there are 52 cards in total and 26 red cards. Probability Red card = (26) / (52) = 1/2 Example 2 A die is rolled. What is the probability that a 6 turns up. There is only 1 six on a die. There are a total of 6 numbers. Probability 6 = (1) / (6) = 1/6 What is the probability of an even number coming up if a die is rolled? There are 3 even numbers on a die. (2, 4, 6) There are a total of 6 numbers. Probability Even number = (3) / (6) = 1/2 Good Luck.

And P is the symbol for probability and ~P is the symbol for not having probability. Fraction form is = Numerator on top and Denominator on bottom, Equvilelent is the fractioned of the same amount. Is some other notes I had on Probability. - DNatureofDTrain
