X - y = 3
x + y = 13
Adding both equations
2x = 16
x = 8
y = 5
Answer:
probability of there meeting = 15/(60-15) = 15/45 = 0.333 = 33%
Step-by-step explanation:
favorable event = +- 15 minutes
total time they can eat launch is between noon and 1pm = 60minutes
they are both known for non punctuality, that means they cant meet up at 12noon, let assume 15minutes pass noon.
probability of there meeting = 15/(60-15) = 15/45 = 0.333 = 33%
which is probably saying they will not meet for lunch that day.

Answer:
![\[\frac{1}{40}\]](https://tex.z-dn.net/?f=%5C%5B%5Cfrac%7B1%7D%7B40%7D%5C%5D)
Step-by-step explanation:
The animal cage contains 5 black cats and 8 white cats.
So the probability of 1 out of 5 black cats escaping can be expressed as ![\[\frac{1}{5}\]](https://tex.z-dn.net/?f=%5C%5B%5Cfrac%7B1%7D%7B5%7D%5C%5D)
The probability of 1 out of 8 white cats escaping can be expressed as ![\[\frac{1}{8}\]](https://tex.z-dn.net/?f=%5C%5B%5Cfrac%7B1%7D%7B8%7D%5C%5D)
The combined probability of 1 black cat and 1 white cat escaping can be expressed as a product of the above two probabilities.
In other words, the combined probability is ![\[\frac{1}{5} * \frac{1}{8}\]](https://tex.z-dn.net/?f=%5C%5B%5Cfrac%7B1%7D%7B5%7D%20%2A%20%5Cfrac%7B1%7D%7B8%7D%5C%5D)
![\[= \frac{1}{40}\]](https://tex.z-dn.net/?f=%5C%5B%3D%20%5Cfrac%7B1%7D%7B40%7D%5C%5D)
