A card is selected at random from a standard deck of cards.Determine each probablity.
P(5), P(red 10) , P(odd Number) , P(queen of hearts or jack of diamonds). :confused: :confused: :confused:

The probability of a discrete event happening is the number of successful outcomes divided by the total possible number of outcomes. Consider rolling a one on a single die. There is one successful outcome (1 is rolled) and six possible outcomes (1,2,3,4,5,6). Therefore, P(1) = 1/6.

Try applying this to a deck of cards, and post your answers. Someone will have a look at them, and help you if you're having any more troubles.
