What is the probability of drawing a heart or a spade when 1 card is picked up from a well shuffled deck?

From a well shuffled and complete deck without the Jokers, pulling one card and getting a heart or spade is one in two. Getting a spade is a one in four shot. (Four suits, equal number of cards in each suit....) Same for club, heart or diamond. Getting a spade or a heart is a one in four plus a one in four or one in two. It's fifty-fifty. The probability of drawing a heart or a spade when 1 card is picked up from a well shuffled (complete) deck (without Jokers) is 0.5 or one half.

What is the probability of drawing 2 hearts and then a spade in that order from a deck of 52 cards?

In order to determine the probability of drawing 2 hearts and then a spade, in that order, from a deck of 52 cards, start by considering the first card. The probability of drawing a heart is 1 in 4. Since you have now reduced the number of hearts and the number of cards in the deck by one, the probability of drawing another heart is 4 in 17. Since you have further reduced the number of cards by one, the probability of drawing a spade is 13 in 50. Multiply these probabilities together, (1/4) (4/17) (13/50), and you get about 0.0153, or about 153 in 10000.
