Answer: Probability that both the pirate and the Captain hit each other's ships is ![\frac{1}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B9%7D)
Step-by-step explanation:
since we have given that
Probability that the captain hits the pirate ship is given by
![\frac{4}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B9%7D)
Probability that the pirate hits the Captains's ship is given by
![\frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D)
So, we have to find the "Probability that both the pirate and the Captain hit each other's ship" is given by
![P(\text{Captain hits})\times P(\text{ Pirates hit})\\\\=\frac{4}{9}\times \frac{1}{4}\\\\=\frac{1}{9}](https://tex.z-dn.net/?f=P%28%5Ctext%7BCaptain%20hits%7D%29%5Ctimes%20P%28%5Ctext%7B%20Pirates%20hit%7D%29%5C%5C%5C%5C%3D%5Cfrac%7B4%7D%7B9%7D%5Ctimes%20%5Cfrac%7B1%7D%7B4%7D%5C%5C%5C%5C%3D%5Cfrac%7B1%7D%7B9%7D)
Hence, probability that both the pirate and the Captain hit each other's ships is ![\frac{1}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B9%7D)
Answer:
-5x^2-2x
Step-by-step explanation:
When distributing, you multiply the term outside the brackets to all the terms in brackets.
If the term outside the bracket is negative, then when distributing/opening the brackets, the signs of the terms changes.
So in this prob. -x would multiply to both +5x and +2
-x*5x+-x*2
∴-5x^2-2x
