assume that you randomly select 4 cards from a deck of 52. what is the probability that all the cards selected are spades?
13
wait
wait, do you replace teh cards each times?
its is not 13
13 is not a probability
9/13
you need to know if you replace the cards: Independent or don't replace: dependent
it doesnt say you do so i assume you dont
its 9/13 try that
that is wrong i tried it
then you didn't write the question correctly?

I don't see how 9/13 is wrong but oh well
in cards of total 52 there are 13 hearts 13 diamonds 13 clubs and 13 spades... the probability of picking up a spade is.... sum of spades/total cards= 13/52= 1/4
Yes 1 spade but he said 4
u take 4 spades then its 13C4/52C4
that did not work either
Okay can you write the whole question, because it changes the way you work it
