## Pascal's triangle

n.
A triangle of numbers in which a row represents the coefficients of the binomial series. The triangle is bordered by ones on the right and left sides, and each interior entry is the sum of the two entries above.

[After Blaise Pascal.]

## Pascal's triangle

n
(Mathematics) a triangle consisting of rows of numbers; the apex is 1 and each row starts and ends with 1, other numbers being obtained by adding together the two numbers on either side in the row above: used to calculate probabilities
[C17: named after Blaise Pascal]
