Probability
The probability of a certain event is a number expressing the likelihood that a specific event will occur, expressed as the ratio of the number of actual occurrences to the number of possible occurrences. In mathematics, it is a measure of how often an event will happen and is the basis of statistics.

What is the probability of independent events?
If you mean the probability that independent events will occur, it is the product of the individual probabilities that they occur. Ex: Probability of picking a red marble from a jar with 4 red and 6 green marbles and picking a black card from a deck of 52.
P(red) = 4/10 = 2/5
P(black card0 = 26/52 = 1/2
P(both) = 2/5 x 1/2 = 1/5

There are approximately 16.4% of students who score below 66 on the exam.
What is the chance of getting an even number when you toss a number cube 10 times?
It is
1 - Prob(No even numbers in 10 throws)
= 1 - [Prob(Not an even number)]10 = 1 - (1/2)10 = 1 - 1/1024 = 1023/1024 or 0.9990
So you are almost certain to get an even number.

What happens in the event of a vacancy occurring in either chamber of congress?
