Answer:
<h2>All real numbers greater than 0</h2>Step-by-step explanation:
The given function is
Notice that the function is exponential, which means its variable is an exponent.
It's important to notice that a power cannot be negative or zero, just positive.
Having said that, all possible results of this exponential expression are elements of the range set.
Therefore, the range must be all real numbers greater than zero.

Answer:
Step-by-step explanation:
Let M denote the event that the stock makes money and D denote the event that the stock pays dividends.
It is given that
Observe that the two events M and D are not independent because if the stock doesn't make money then it will not pay dividends. Therefore the event (D given M does not occur) is a null event, i.e
It is also given that,
Recall that :
Here, we are required to find
