I NEED FAST HELP WILL GIVE MEDAL

OpenStudy (ashontae19):

Can someone please help me

OpenStudy (ashontae19):

@mastermindkakashi

OpenStudy (ashontae19):

@misssunshinexxoxo

OpenStudy (anonymous):

i think its a

OpenStudy (ashontae19):

thank you can you answer one more

OpenStudy (anonymous):

lol ok

OpenStudy (anonymous):

also that soda pop question: you'd take the chance of each outcome and multiply

OpenStudy (anonymous):

so that would be 0.02*0.98 = ? (the 0.98 comes from the chance that the soda is filled, so .100-.02)

OpenStudy (ashontae19):

you want me to answer?

OpenStudy (ashontae19):

0.0196

OpenStudy (anonymous):

yep! you were right the first time

OpenStudy (anonymous):

and the second one you sent, you basically just combine all the sets

OpenStudy (anonymous):

just as long as it includes all the numbers

OpenStudy (ashontae19):

so it not a???? and can you help me because im in a rush and i dont want to miss anything out

OpenStudy (anonymous):

which question are you speaking of?

OpenStudy (ashontae19):

the sets

OpenStudy (anonymous):

the set one should be C, but thats because it includes the 6

OpenStudy (ashontae19):

so how i did you do that

OpenStudy (anonymous):

you just look at the numbers in all the sets and combine them together since it asks for A U B U C. that means the union of all those, so basically all the numbers included in those sets

OpenStudy (ashontae19):

so add all the sets and what

OpenStudy (anonymous):

well not add them as in add the values, just combine the sets, excluding duplicates

OpenStudy (anonymous):

in all those sets, we have a 1, 2, 3, 4, 5, 6, and a 7. so the answer should include all of those

OpenStudy (anonymous):

for the first one, you multiply the probability of him making the goal by the probability of him making the goal each time he tries

OpenStudy (anonymous):

sorry if that doesnt make sense

OpenStudy (anonymous):

basically since he has the same probability of making the goal each time, it would be 0.75*0.75*0.75

OpenStudy (ashontae19):

im really in rush to be honest i did all the work i just want to know if i am right

OpenStudy (anonymous):

what did you get for that one?

OpenStudy (ashontae19):

3/8

OpenStudy (anonymous):

I got 27/64th

OpenStudy (ashontae19):

for the sets a and c i got c is that correct?

OpenStudy (ashontae19):

it was the second question i posted

OpenStudy (anonymous):

ah for the set one, since it's not union this time, its the intersection, so between the two sets A and C you just want to find what numbers the two sets have in common

OpenStudy (ashontae19):

so the answet would be???

OpenStudy (anonymous):

so just 2 and 3

OpenStudy (ashontae19):

ok thank you i was just about to type that

OpenStudy (ashontae19):

for the third one a and b i got d

OpenStudy (anonymous):

and for the third set one, it would be the combination

OpenStudy (anonymous):

thats exactly right

OpenStudy (ashontae19):

thank you for the deck of cards the last one i got 1/8

OpenStudy (anonymous):

now for the last one

OpenStudy (anonymous):

since there's 8 outcomes that fit for that and 52 total cards, you'd take 8 over 52 and just reduce it

OpenStudy (ashontae19):

2/3?

OpenStudy (anonymous):

2/13

OpenStudy (ashontae19):

2/13

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

is that all?

OpenStudy (anonymous):

it would be B on that one. as long as x is a vowel, which is what that set contains

OpenStudy (ashontae19):

ok thank you so much
