For the roll of a pair of dice, the sums will be in a set from 2 (both dice give you a 1), the smallest sum possible, to 12 (both dice give you 6), the largest sum possible.
In a fair experiment, all possible outcomes are equally likely.
The sample space for getting either a sum of 7 or a sum of 11 is the union of both sets.
Probability and statistics concepts are tested as one of the strands of SAT Mathematics.
The probability of any outcome is related to the total number of outcomes by a ratio of the number of outcomes in that event to the number of all possible outcomes of the event (the sample space).

Therefore, the probability that a coin will be heads is 1/2.The probability that if one die is rolled, the number on top will be a 3 is 1/6.Sometimes, possible outcomes can be combined in such a way so that not all outcomes are equally likely.Suppose two fair coins are tossed: there are 4 possibilities in the sample space .The probability of each event when order is important equals 1/4 for each possibility.For a coin toss, the coin will either result in heads or tails.For the roll of one die, the sample space is all the values on the faces of the die, or a set of .Topics include measures of central tendency such as mean, median, and mode; elementary probability; and geometric probability.The test doesn’t contain long calculations of standard deviation or other statistical measurements.The event 0 heads is defined as , and the event 2 heads is defined as .However, there are two possibilities for 1 head, either or , so the outcomes are not equally likely.
