It does not matter.
a and b both have the probability of 3/4
The probability that an event will occur plus the probability that it will not occur equals 1.
0.8413
The probability is 0.664
Probability equals favorable outcomes divided by total number of outcomes.
Impossible
The answer depends on what the distribution is!
The probability of no rain is the complement of the probability of rain. If the probability of rain is 0.99, then the probability of no rain is calculated as 1 - 0.99, which equals 0.01. Therefore, there is a 1% chance of no rain.
The number 1. The area of any probability distribution equals 1.
From a probability perspective fair means equal probability.
