Question

What is the theoretical probability of drawing an ace from a standard deck of playing cards?
A. 1/52
B. 1/13
C. 1/4
D. 4/13

Answer 1

Remember there are 4 aces in a deck. So the theoretical probability would be B. 1/13

Answer 2

what makes it theoretically though ?

Answer 3

This basically states if you take a deck and draw 13 cards one will be an ace. This may be possible with a perfectly shuffled deck, but most likely you will got more than one ace or no aces.

Answer 4

oh, okay. so could you help me with one more question quick, i think i know what it is, but id like to double check my answer ?

Answer 5

shoot

Answer 6

Your little brother bets you that if he flips a coin 4 times, he will get "heads", 3 times. You know the theoretical probability is in your favor. Which of the following is your best response to his challenge?
A. Take the bet...there is no way that theoretical probability can be wrong
B. Do not take the bet...the sample size (only 4 flips) is too small
C. Flip a coin 4 times yourself and then decide
D. Take the bet and if you lose, accuse your brother of having a fake coin

i think its B, cause the others seem kind of silly, but it could b C as well.

Answer 7

I agree with B. if you flipped the coin 100 or more times then theoretical probability would be closer to correct, but a sample size of 4 makes it pure luck. Flipping the coin for yourself wouldn't really prove anything in this case since your sample size is also too small.

thank you! (:
