Answer:


Detailed steps:
We know that the number of total events is

and that the probability of a certain event E (for example, "<em>the enemy drops two objects</em>") is computed as the number of times event E occurred, divided by the total of events N=80.
Then:


and

We can verify by checking that adding all probabilities sums up to one.
Answer:
x = ± 15
Step-by-step explanation:
Given
x² = 225 ( take the square root of both sides )
x = ±
= ± 15
That is x = - 15 0r x = 15
The change in x from A to B is positive. The line is going up, so the slope cannot be negative
