so this is similar to the last one. you want to know how many possibilities there are that a given event happens (in this case red 5-9), and how many possibilities there are total. The first things you need to determine are: 1. how many red cards are there between 5 and 9? 2. how many total cards are in the deck?
well how many red cards are there in a deck .. is it 26 >?
right, so there are 5,6,7,8,9 of diamonds and hearts
so 10 total that are red AND 5-9
there are 52 cards in the deck total
so the probability of a red card that is 5-9 = 10 (the number of red 5-9)/52 (total number of cards)
yay I get it!
how did you get 10?
well, in a deck of cards, the red cards are diamonds and hearts
so there are two sets of 5-9 that are red - hearts and diamonds
so in total, there are 5,6,7,8,9 of hearts, and 5,6,7,8,9 of diamonds, so 10 total
so the probability = (possible red 5-9) divided by ( total possible cards)
man i hate card problems.. how the heck would i know how many cards are there...I mean gambling is illegal in schols..
true - so (a) = 10/52
so how do you think you get b?
how do i rememeber all those red cards and everything?? coz itss hard :"S
well, the good news is that a deck of cards is used across a LOT of probability questions
is it lik 10/52 * 75 ?
so you just gotta know - there are 52 cards, 4 suits, 2 suits of each color, 13 cards in each suit
and yes, you are correct
so good work =)
whoz rigjht me???
thats amazing :O
it happens :p and it will happen more the more you practice
and i still dont get it.. maybe im not tryin hard enough =/
embarassin really, bein good in calc and when someone asks me a stat question i gtg.. sorry i dunno..
haha, well if you asked me a calc question I'd give you a blank stare :p
i got aniother questin too
k, I'd say ask a different one on the left side
and I'm sure many of us will make the jump
ok make sure that uhelp me lol
ur supposed to be asking another question
shes tryin to do it on her own
