Answer:

Following are the solution to the given points:

Step-by-step explanation:

In point a:

It's also expected that approximately $1000 \times 0.40 =400$ of both, the students contribute zero, approximately $1000 \times 0.30 =300$ to donors $10, approximately $1000 \times 0.25 = 250$ donors $25, and then about $1000 \times 0.05 = 500$ dollars $50 donors. Its frequencies would be similar to and not precisely, the probability. The four levels will stack up to a thousand.

In point b:

It is the population, in which the key value of x is a $0 donation ( 40 percent of students do this).

In point c:

$\to P(X \geq 25) \\\\\to 0.25+0.05 \\\\\to 0.30$

In point d:

$\to P(X>0)\\\\ \to 1-P(X=0)\\\\ \to 1- 0.40\\\\\to 0.60\\\\$
