Answer:
3 ways
Step-by-step explanation:
How many different ways can you place 4 identical marbles in three jars shown below? Note: Every marble needs to be in one of the jars, but not every jar needs to have a marble in it.
We solve using combination
n-1 C r-1 = nCr = n!/r! (n - r)!
n = 4 identical marbles
r = 3 jars
Hence:
4 - 1 C 3 - 1 = 3C2
= 3!/2! (3 - 2)!
= 3 ways
well, 6.2% of 4,300 can't be over half. she has made a calculation error, and the real answer is (this is where the mistake was made) 4,300 * 0.062 (not 6.2, because percents are always divided by 100 to make them into a usable number), which is equal to $266.60.
