P(not graduate) = 1 - P(graduate) = 1 - 0.9 = … The chance of rain is very slim. The words ‘probably’, ‘doubt’, ‘most probably’, ‘chances’, etc., used in the statements above involve an element of uncertainty. We then compute the probability of that value occurring in the data.

Let us specify a “flat” probability distribution in each case, such that each element in the two pairs corresponds to a probability of 0.5. We are predicting rain today based probability (using fraction or decimal) could be: It is most likely going to rain tomorrow. A probability is a number that tells you how likely (probable) something is to happen. There are many other examples of classical probability problems besides rolling dice. ... this gives us the likelihood of each event occurring with a “Rain Tomorrow (RT)” probability of 22%. Probability and Statistics for Engineers and Scientist - 9th Edition (by Walpole, Mayers, Ye) Omar Al Javed. All you can tell is you are likely to see some sort of precipitation. For example, in (1), ‘probably rain’ will mean it may rain or may not rain today . The probability of this happening is 1 out of 10 lakh.
