There are 12 months. Out of those January, February, May, and July end in Y.
4/12 = 1/3 of the time a randomly selected month will end in Y.

The probability that a letter picked at random is not a vowel depends on the set of letters you are choosing from. In the English alphabet, there are 21 consonants and 5 vowels, so the probability of picking a consonant is 21/26 or approximately 0.808.
the letter a
The answer depends on how many cards are picked, whether they are picked at random, from what sort of pack, and whether or not cards are replaced before the next one is picked. The probability that a single card, picked at random from a regular 52 card deck is red, is 0.5
If the winning numbers are picked at random, the probability is 1 in 169911.

There are 4 months that end in the letter Y, January, February, May, and July. The probability, then, of a random month ending in the letter Y is 4 in 12, or 1 in 3, or about 0.3333.
If picked at random, the answer is 2/11.
The answer depends on how many cards are picked, whether they are picked at random, from what sort of pack, and whether or not cards are replaced before the next one is picked. The probability that a single card, picked at random from a regular 52 card deck is red, is 0.5
If the winning numbers are picked at random, the probability is 1 in 169911.
For a single card, picked at random from a well shuffled normal pack the probability is 3/13.
