Answer:
You can decorate the weeding in 240 different ways.
Explanation:
Since you are planning table decorations for a wedding, and you must have at least one thing on the table, and you have 5 identical candles, 4 identical pictures, 3 identical flowers, and 4 identical bowls to choose from, to determine how many ways can you decorate the following calculation must be performed:
5 x 4 x 3 x 4 = X
20 x 12 = X
240 = X
Therefore, you can decorate the weeding in 240 different ways.
