Answer:
Total 15 ways are possible to select two investments of $30,000 each.
Step-by-step explanation:
An investor would like to invest $60,000 in 2 stocks from a list of 6.
Amount of each investments is $30,000.
If we need to select r its from n items, then
[tex]^nC_r=\frac{n!}{r!(n-r)!}[/tex]
We have to select 2 stocks from 6.
[tex]^6C_2=\frac{6!}{2!(6-2)!}[/tex]
[tex]^6C_2=\frac{6!}{2!4!}[/tex]
[tex]^6C_2=\frac{6\times 5\times 4!}{2\times 1\times 4!}[/tex]
[tex]^6C_2=15[/tex]
Therefore, total 15 ways are possible to select two investments of $30,000 each.
