You pick a card at random.123What is P(2 or odd)?

Solution

The question seems to be about the probability of drawing a card that is either a 2 or an odd number. However, the question is not clear about the total number of cards or the range of numbers on the cards.

Assuming we are dealing with a standard deck of 52 playing cards, the probability of drawing a 2 is 4/52 (since there are 4 twos in the deck).

The probability of drawing an odd card (assuming Ace counts as 1, and only considering numerical cards, not face cards) would be 20/52 (since there are 5 odd numbers (Ace, 3, 5, 7, 9) each in 4 suits).

However, we can't simply add these probabilities together, because they overlap (the 2 is an even number, not odd). So the probability of drawing a 2 or an odd card remains 20/52, or approximately 0.385, or 38.5%.

If the range of numbers on the cards is different, the calculation would need to be adjusted accordingly.
