Answer:
The random variables in this case are discrete since they have a Multinomial distribution.
The probability mass function for a discrete random variable X is given by:
Where are are possible values of X.
The joint probability mass function of two discrete random variables X and Y is defined as
P(x,y) =P(X=x,Y=y).
It follows that, The joint probability mass function of is :
we are given
investment amount is 2300
so,
it is compounded monthly
so,
n=12
now, we can use formula
now, we can plug values
t=7/12
and we get
now, we can find FV
