WebJul 17, 2024 · The probabilities of two events (tossing a coin and throwing a dice) are represented individually. You can be surprised that I displayed the probabilities in a table. Actually, I took the problem backward: these probabilities are the marginal probabilities. The name ‘marginal’ reminds the idea that we can write them in the margins of the table.
WebIf we don't observe x, that probability is: > mean( rolls $ y ==1) 0.16602. If we know that x=3, then the conditional probability that y=1 given x=3 is: > mean( rolls $ y [ rolls $ x ==3]==1) 0.165793. These results are very close. Note: R makes it very easy to do conditional probability evaluations.
