Number of Permutations of N Different Things taken R at once given One Specific Thing Always Occurs Solution

Follow our step by step solution on how to calculate Number of Permutations of N Different Things taken R at once given One Specific Thing Always Occurs?

FIRST Step Consider the formula

P = (r!) \cdot \frac{(n - 1)!}{(n - r)! \cdot (r - 1)!}

Next Step Substitute values of Variables

∴

P = (4!) \cdot \frac{(8 - 1)!}{(8 - 4)! \cdot (4 - 1)!}

Next Step Prepare to Evaluate

∴

P = (4!) \cdot \frac{(8 - 1)!}{(8 - 4)! \cdot (4 - 1)!}

LAST Step Evaluate

∴

P = 840
