i did this research and made my own equation on my own, take our Galaxy for example
1 galaxy=150-350 billion stars
lets take 250 billion stars, and if each star has a solar system of 1 to 9 planets, lets say each star has 5.
5 planets times 250 billion stars = 1,250 billion planets
and if at least 1 in 5 planets has life on it
1/5 X 1,250 billion planets = 250 billion planets
so i think maybe at least 250 billion planets in OUR galaxy have life
but that's only our Galaxy (Milky Way) and in the universe there are billions of galaxies maybe trillions, and how do we know this is the only universe, could there be more?

What are real life examples of probability?
# of successes = probability or change total
What is probability in everyday life?
Probability in real life can be said as something that usually happens. No one can predict the future, however; one can determine how likely it is that something will or will not happen.
What is the probability that the life of a single tire will be less than 39200 miles Sampling distribution mean life of 40000 miles with a standard deviation of 4620 miles?
The probability is 0.4312
Who uses probability?
No one! It's pointless in life and will get you nowhere.
Relation between expected return in real life and probability?
no
