Final answer:
The expected sales of the Arum company next year is $6.9 million, which is closest to option a) $6 million.
Step-by-step explanation:
To find the expected sales of the Arum company next year, we need to multiply each possible sales amount by its corresponding probability and then add them together. The expected sales can be calculated as follows:
Expected Sales = (Sales Amount 1 x Probability 1) + (Sales Amount 2 x Probability 2) + (Sales Amount 3 x Probability 3)
Expected Sales = ($10 million x 0.50) + ($5 million x 0.20) + ($3 million x 0.30)
Expected Sales = $5 million + $1 million + $0.9 million
Expected Sales = $6.9 million
Therefore, the expected sales of the Arum company next year is $6.9 million, which is closest to option a) $6 million.
