Question

I need help with probability and the counting principle

Answer 1

how sophisticated do you need to go?

Answer 2

I got a rudimentary understanding of probability

Answer 3

6th grade level
it doesn't make sense to me

Answer 4

give us a problem and lets see if we can work thru it :)

Answer 5

ok thanks

Answer 6

how many different words can be
made using the words quick, slow, and sad and the suffixes
-ness, -er, and -ly.

Answer 7

is the answer 9

Answer 8

so we have 4 words, and 3 endings. right?

each word can be made 3 times; sadness, sadder, sadly...

you do that 4 times and you get 12 words.


theres a "tree" you can form" but Id have to go to paint to do it...

Answer 9

three words and three endings

Answer 10

yeah...I saw 4 words...that was my mistake :)

Answer 11

the concept is the same tho....so yeas, 9 :)

Answer 12

this is difficult to explain without drawing pictures

Answer 13

I need to know the probability of two colored spinners and stuff like that

Answer 14

write it out, lets see if I can understand it :)

Answer 15

Great! Thanks for being so patient

Answer 16

Here goes...

Answer 17

a coin is tossed, and a letter is
chosen from a bag . The letters in the bag are X, P, Z, K, M, A, E, Y
11. How many outcomes are possible?
12. Find P(heads, E).
13. What is the probability of tails and P, Z, or M?

Answer 18

I don't understand what the coin has to do with it

Answer 19

I'm never gonna get this

Answer 20

the coin is jsut an additional "variable" in it....

you start with the coin toss, which is 50% chance of getting heads or tails right?

Answer 21

yes

Answer 22

ther are 2 outcomes from the coin toss, and 8 outcomes from the letters in the bag right?

16 outcomes total correct?

Answer 23

I think I was making it harder thatn it actually was

Answer 24

thank you

Answer 25

youre welcome, sometines all it takes is a fresh set of eyes :)

Answer 26

but wait

Answer 27

Can I just run this by you to make sure I understand everything

Answer 28

P(heads,E) I would assume means (100/2,100/16)

sure run it by me..

Answer 29

50% and 100/8 actually... 12.5%

P(50%,12.5%)

Answer 30

yikes I think I'm lost again

Answer 31

how did you get 100 over 8

Answer 32

I dont quite understand the notation P(heads,E) but to me it would mean that there is a 1 in 2 chance of getting heads: 100/2 = 50%

and a 1 in 8 chance of getting an "E"; 100/8 = 12.5%

Answer 33

oh ok

Answer 34

100 is just the "percent" number.... I use it to adjust for the "chances" into an actual percentage

Answer 35

what are independent vs. dependent events

Answer 36

Believe it or not I do well in math but this probability stuff is confusing to me

Answer 37

when 2 things happen without a cause, they are independant of each other. The snow falling in alaska and my shoe coming untied in NewYork are not related, they are independant of each other.

the opposite of that is events that occur because of the other. like:

The light was off, I stubbed my toe.

Answer 38

cool analogy but how do I apply it to this unit on probability
