... Suppose that when we pick 3 letters out of the 6 letters A, B, C, D, E, and F we chose BCD, or BDC, or CBD, or CDB, or DBC, or DCB. (These are the 6 (3!) permutations or orderings of the 3 letters B, C, and D.) But these are orderings of the same combination of 3 letters. How many combinations of 6 ...

Probability: Terminology and Examples Class 2, 18.05 Jeremy Orloff
... Challenge 1: show the sum of all the probabilities equals 1 (hint: geometric series). Challenge 2: justify the formula for P (n) (we will do this soon). Stopping problems. The previous toy example is an uncluttered version of a general class of problems called stopping rule problems. A stopping rule ...

... the sample space is not equally likely. One method to determine the probabilities of the outcomes is to make a list of all the possibilities. For example, (1, 1) could represent rolling a 1 on the first number cube and a 1 on the second number cube. Another example, (1, 2) could represent rolling a ...

... The problem for statistics is determining the value of this parameter p. All we know is that it lies between 0 and 1. We also expect the ratio k/n of the number of successes k to the number trials n to approach p as n approaches ∞, but that’s a theoretical result that doesn’t say much about what p i ...
