$n!$ is the product of the first $n$ positive integers for $n\ge 1$.\( n!=n(n-1)(n-2)(n-3) \cdots \times 3 \times 2 \times 1 \)$n!$ is read “$n$ factorial”. For example, the product $5 \times 4 \times 3 \times 2 \times 1$ can be written as $5!$.Notice that $5 \times 4 \times 3$ can be written using factorial […]

Probability with Replacement

Probability with Replacement

August 26, 2016 0 comments

Probability with Replacement is used for questions where the outcomes are returned back to the sample space again. Which means that once the item is selected, then it is replaced back to the sample space, so the number of elements of the sample space remains unchanged. A jar contains five balls numbered 1, 2, 3, […]
