Answer 1

@ybarrap

Answer 2

b/y

1/2

Answer 3

how did u get that

Answer 4

there is one blue and one yellow...that is 2. if you roll both its a 50 50 chance so 1/2

Answer 5

ok thnk u

Answer 6

yeahhhhh:)

Answer 7

what abt this?:

Answer 8

You roll two dice. Let event A be "The first die shows a 1 or a 6" and event B be "The second die shows an even number." What is P(A | B)?

Answer 9

In the first problem, if the blue die lands 2 then in order for the sum of the blue and yellow to be 6 or greater, the yellow needs to be a 4, 5 or 6, since 2 + 4, 2 +5 and 2 + 6 are all sums greater than or equal to 6, The chance that yellow is 4,5 or 6 is 3/6 or 1/2.

Answer 10

its not 1/3??

Answer 11

its 1/2 sleek-feathered one

Answer 12

No @MROAKS1432 the answer is 1/3

Answer 13

how did u get that

Answer 14

Because if P(A) = P(1 or 6) then:
P(1) + P(6) and then you can get your answer:
(1/6)+(1 / 6) = 2/6 =1/3

Answer 15

so it is 1/3. @ybarrap i don't really understand wat u said though

Answer 16

Answer 19

thanks. can any of u guys open the attachment??? :(

Answer 20

My reply above was for your first problem.
For the second problem P(A|B) = P(A and B)/P(B), but each are independent, so
P(A|B) = P(A)P(B)/P(B) = P(A) = P(1) + P(6) = 1/6 + 1/6 = 1/3 as @AwesomeB stated

Answer 21

yay :)

Answer 22

ok what abt the ATTACHMENT above

Answer 23

ill repost it as a new question & then i'll tag u guys??
