A boy has in his pocket a 50-cent piece, two dimes and two pennies. If he pulls out a coin at random, what is the probability it is worth at least ten cents?
Again?
yeah im trying is it 2/5 @royalranger
wait did i do this problem already?
@royalranger can you help me with probability and percentages?
How many coins are worth at least 10 cents?
1 dime
oh its 1/5 ohhhh
Two cards are drawn at random from a standard deck of 52 cards, without replacement. What is the probability that both cards drawn are hearts? (There are 13 hearts in a standard deck of cards.)
can you help me with this?
Its not 1/5. It asks you how many coins are worth AT LEAST 10 cents? Well there are 2 dimes, those are worth at least 10 cents. And the 50 cent coin is worth more than 10 cents. So we have a total of 3 coins that are worth at least 10 cents.
oh im stupid @royalranger thanks
