What is the probability that one card is the hand is jack of hearts?
a hand has 5 cards
it it 1/ 52C5 ?
rawrrr i dont think thats correct
am i completely off?
so what is the probability of Jack and Queen of hearts?
hmmm i dont think i agree with you
show me what u got in mind
1/52 x 1/51 x 1/50 x 39/49 x 38/48 x 5!
= 5/52 x 4/51 x 3/50 x 2*39/49 x 38/48
Interesting .... This is what I got Total sample space is 52C5 right?
like we have 52 cards and we only choose 5
Event A = Picking Jack of hearts, King of hearts and Queen of hearts and 2 other cards that are not a heart Event A = 1*1*1*(52-13)*(52-14) Event A = 1*1*1*39*38 Probability of Event A = Event A /Total Sample Space =(39*38)/(52C5)
Our results agree.
19/ 33320 = 0.0000570....
I guess in that case i can assume that my method is correct Just for curiosity sake I would love to understand your method
Why you multiplying by 5! at the end?
because the 5 cards can be in any order
Oh ok i Get what you did .... Thanks
k I got one more question
Five students are randomly selected from seven boys and six girls to join a ski trip. What is the probability that All are girls
6/13 x 5/12 x ...
Im just wondering if I was to use my method what would be the total sample space
13 C 5?
how abt the girl and boy thing and divided into groups
ughhhh ur right -.-
dang it it was sooo simple
Gonna drive you insane one last time butttttt What is the probability if there were more boys than girls In that case we gotta look at 3 options : 5 Boys 0 Girls, 4 Boys and 1 Girl , 3 Boys and 2 Girls So in this event you would take the probability of each scenario and then sum them all up correct?
that will work
how were you thinking of approaching this problem?
there are only the three cases to consider, so this is probably the easiest way
Ok Thanks!!!!!!!!!! I really appreciate it that you took the time to help me
