MaRussiya [10]

Answer:

32768 ways

Step-by-step explanation:

Given

Marbles = 8 marbles

Selection = 5 (with replacement)

Required

Determine the number of ways

Because it is a selection with replacement; each selection is as follows:

$First = 8\ marbles$

$Second = 8\ marbles$

$Third= 8\ marbles$

$Fourth = 8\ marbles$

$Fifth = 8\ marbles$

Total number of ways is then calculated as:

$Total = 8 * 8 * 8 * 8 * 8$

$Total = 32768$
