Probability and decks of cards.....

[lasonya39]

I really need help with the following questions:


Find the probability of the given event:

1. One card drawn from a well-shuffled deck of 52 cards is a face card or a 4.
2. One card is selected from a deck of cards. Find the probability of selecting a black card or a queen.

Any assistance provided, I would appreciate it.

1. One card drawn from a well-shuffled deck of 52 cards is a face card or a 4.

How many cards are face cards? How many cards are fours? So how many cards are face cards or fours?

How many cards are in the deck? So what is the probability that the card drawn from the deck will be a face card or a four?

2. One card is selected from a deck of cards. Find the probability of selecting a black card or a queen.

How many of the cards are black? How many of the cards are queens? Now, to eliminate over-counting, how many of the cards are black queens? So how many cards are black or queens?

How many cards are in the deck? So what is the probability that the card drawn will be black or a queen?
