The probability that a single person would like at least ONE flavour - is 9/10

No.
350 liked only Vanilla
250 liked Vanialla and Chocolate
50 liked only Chocolate
That makes 650 [the remaining 350 did not like either].
Therefore the probability that a randomly selected person likes at least one of the two tastes is 650/1000 or 65%
An empirical estimate of the probability of an event is the ratio of the number of succesful outcomes to the total number of trials. By definition, the ratio is a fraction. However, there are many events for which the theoretical probability is related to irrational numbers. For example, it you randomly drop a pin on a floor of wooden boards, the probability that the pencil lies across a lateral join is related to pi. Being irrational, this cannot be expressed as a fraction.
As all the angles in a square measure 90°, the probability of 2 randomly chosen angles being congruent is 1.

If you randomly pick a card from a standard deck of cards, that probability will be 1/4, since 1/4 of the cards are heart.
If the events can be considered independent then the probability is (0.7)4 = 0.24 approx.

Non probability sampling is where the samples are not selected randomly.

Assuming then that there are 100 numbers, 1-100, the probability of the number 23 being randomly picked out of 100 is: 1/100 or 0.01.
