Answer 1

not working dear
maybe a screen-shot would be better

Answer 2

oh ok thank you :)

Answer 3

A) how many have animal mascots? and what is the total number of teams/

Answer 4

42/122

Answer 5

There are 42 that have animal mascots out of 122 total. Thus, the probability of picking one with an animal mascot=42/122. Is this greater or less than 1/3?

Answer 6

For the next one, how many are cities with animal mascots? How many is the total of everything?

42/122 > 1/3

36/122 < 1/3

6/20 < 1/3

36/102 > 1/3

Answer 9

so I was correct then :) thank you

Answer 10

Or, we are both incorrrect. I showed my work.

Answer 11

lol yeah we were correct that was my last question for that lesson :) can I add one more question to this thread? and I will give you your medals of course :)

Answer 12

1) P=(A|B) = P(A ∩ B)/P(B)

(.30 * .75) / .75 = .3

See if you agree with that.

Answer 13

yes I do agre and I'm sorry I'm a bit late in replying but I was translating something for my mom

Answer 14

2) Same formula

(.75 * .30) / .30 = .75

Answer 15

3) Do you think we read the 1% right out of the chart?

Answer 16

yes it is 1% and I'm so sorry I space out and I was doing other math question

Answer 17

D) .01/.30 = .03 Questionable Answer

Answer 18

E) .75 * .02 / .03 = .5 Very Questionable Answer

Answer 19

ok let me check

Answer 20

shouldn't it be 3/30 for D?

Answer 21

F) .02(.03)/.75 = .0008 Questionable

Answer 22

>>shouldn't it be 3/30 for D?

You ask that but do not show any work.

Answer 23

because 3% for resulted in a home run and 30% for involving a left handed

Answer 24

Answer 25

@ganeshie8

Answer 26

1) P(A|B) = P(A ∩ B)/P(B)
= 24 / 75
= 0.32

Answer 27

ok so that one is correct but what about the ones that directrix had questions on mainly D

Answer 28

that one is not correct, please go through again

Answer 29

1)

A : left hand hitter
B : right hand pitcher

from the given table,
75% involved right hand pitcher, so P(B) = 75%
24% involved left hand hitter and right hand pitcher combo, so P(A ∩ B) = 24%

P(A|B) = P(A ∩ B)/P(B)
= 24 / 75
= 0.32

Answer 30

oh ok so its not 0.3 but 0.32 is that what you meant?

Answer 31

Yes, and do you get how to work the conditional probability ?

Answer 32

I think so let me try the second one

Answer 33

so the second one is 24/30?

Answer 34

Perfect!

Answer 35

ok can you stay and revise the rest please

Answer 36

then 1/3?

Answer 37

Yep, keep going..

Answer 38

1/30?

Answer 39

Yes

Answer 40

omg thank God lol I wasnt sure about that one xD

Answer 41

Answer 44

@ganeshie8

Answer 45

Answer 46

alright thank you very much :D

Answer 47

Answer 50
