Answer 2

A conditional probability is basically something like... This could happen, as long as this did.
There's only one answer that has that type of structure. Know which one?

Answer 3

B"

Answer 4

?

Answer 5

Exactly

Answer 6

thanks man. u always come through

Answer 7

u should be a qualified helper

Answer 8

No problemo

Maybe one day. This is just my second day here. It's addicting to me lol

Answer 10

do you have time for a couple more?

Answer 11

Sure

Answer 12

can be read as "the probability that A occurs given that B has occurred."

A. True
B. False

Answer 13

P(A|B)

Answer 14

is in the beginning

Answer 15

Yes. It's true if this is still about conditional probablities

Answer 16

ye that one was ez

Answer 17

u got soundcloud?

Answer 18

Yeah, I haven't posted anything there for like 6 months (Nothing serious for 8 months)

Answer 19

damn, u dont want this work in a rap battle

Answer 20

What is the probability of rolling a number greater than or equal to 8 with two dice, given that at least one of the dice must show a 6?
9/11
2/11
7/11
4/11

Answer 21

9/11?

Answer 22

Hmm, I don't know about this one.

Since 1 must show a 6, that makes the probability 1/6.

8-6 = 2

That means the second dice must show a 2 or greater in order to meet this requirement.

2,3,4,5,6... that's 5 numbers, so 5/6 for the second dice.

But, that doesn't match

Answer 23

yea this website my school uses is dumb

Answer 24

If there is a 90% chance of rain tomorrow and a 70% chance of wind and rain, what is the probability that it is windy, given that it is rainy? Round your answer to the nearest percent.

A. 78%
B. 33%
C. 71%
D. 67%

Answer 25

D?

Answer 26

Yeah, I never took Statistics, so I'm limited there


I would convert those numbers to equal out of 1, not 100. So you would get .9 and .7. Then divide those two numbers (.7/.9)

Remember to round

Answer 27

1 more please?

Answer 28

According to the general equation for conditional probability, if p (a^b')=1/6 and p(b')=7/24 , what is p(a[b) ?
3/7
4/7
5/7
2/7

Answer 29

2/7?
