The answer depends on what you are selecting from. If you are selecting months in which the equinoces occur, the probability is 0.5
The probability is 0.4231, approx.
The probability of selecting a red card is 26 in 52 or 1 in 2. The probability of selecting an even card is 20 in 52 or 5 in 13. The probability, therefore, of selecting a red even card is 1 in 2 times 5 in 13 or 5 in 26.
The probability is 6/52 = 3/26.
From a 52 card deck, probability is 1/52.

Total number of months we use to have = 12. The month for required event is march. Quantity is one. Therefore, required probability = 1/12.

The statement about the probability of selecting the letter 'z' from the alphabet being 126 is incorrect. The probability of selecting any one specific letter from the 26 letters of the English alphabet is 1/26, not 126. Therefore, the probability of selecting 'z' is approximately 0.0385, or about 3.85%.
The probability is 0.
It is 3/4.
The probability is 2:7.
