HELP PLS I NEED THIS >3

Answer 1

56

Explanation:

Here, n = 8, r = 3

`\huge \orange{ \because \: ^nC_r = (n!)/(r!(n - r)!) } \\ \\ \huge \therefore \: ^8C_3 = (8!)/(3!(8 - 3)!) \\ \\ \huge \therefore \: ^8C_3 = (8 * 7 * 6 * 5!)/(3 * 2 * 1 * 5!) \\ \\ \huge \red{ \boxed{\therefore \:^8C_3 = \purple{56}}}`
