3 cards are drawn at random from a standard deck. Find the probability that all the cards are hearts.

Find the probability that all the cards are face cards.

Note: Face cards are kings, queens, and jacks.

Find the probability that all the cards are even.

(Consider aces to be 1, jacks to be 11, queens to be 12, and kings to be 13)

Answers

Answer:

i dont really understand what you mean it says 3 cards are drawn and it says to find the probability that the cards are all hearts but what is the question asking how do we find the probability

Step-by-step explanation:

Final answer:

The probabilities of drawing all hearts, face cards, or even cards are calculated with the formula: $(n/52) * ((n-1)/51) * ((n-2)/50)$ where n is the total number of cards that match the desired outcome.

Explanation:

The subject here is probability, specifically, how to determine the likelihood of a particular outcome when drawing cards from a standard deck. Let's deal with each probability one at a time.

The probability that all the cards are hearts: There are 13 hearts in a deck of 52 cards. So the probability that the first card is a heart is 13/52, the second is 12/51 (because one heart is already drawn), and the third is 11/50. So, the overall probability is $(13/52) * (12/51) * (11/50).$
The probability that all the cards are face cards: There are 12 face cards (kings, queens, and jacks) in a deck. Using the same principle, the probability is $(12/52) * (11/51) * (10/50).$
The probability that all the cards are even: The 'even' cards are 2, 4, 6, 8, 10, which have 4 of each (hearts, diamonds, spades, clubs) totaling 20 cards. So, the probability is $(20/52) * (19/51) * (18/50).$

What are three consecutive integers whose sum is 138? Write and solve an equation with one variable. What are three consecutive integers whose sum is 138? Write and solve an equation with one variable.

Answers

x + (x+1) + (x+2) = 138
combine like terms
3x + 3 = 138
subtract 3
3x = 135
divide by 3
x = 45

so the three numbers are 45, 46, and 47
