I mean A is my answer

Answer 2

@pgpilot326 is A correct?

Answer 3

we must unite them into 1 meaning independent right?

Answer 4

the event less than 3 and the event more than 4 are not independent

Answer 5

union?

Answer 6

try again ;)

Answer 7

hmmm im gona go with a mautual exclusive?

Answer 8

they cannot both occur simultaneously.... thus they are _____________ events.

know your defs!

Answer 9

dependent?

Answer 10

because they depend on eachother?

Answer 11

you have to work from the definitions. independence and dependence is defined in terms of probabilities.

if A and B are independent events, then P(A)*P(B) = P(A and B)

if they are dependent, then P(A and B) does not equal P(A)*P(B).

mutually exclusive events means that A and B cannot both occur simultaneously. This implies that P(A and B) = 0.

Union is just P(A or B) = P(A) + P(B) - P(A and B)

Answer 12

okay but dependent is the right answer right?

Answer 13

no

Answer 14

okay then it has to be mutal exvlusive like i had said above

Answer 15

event A: player rolls a number less than 3.
event B: player rolls more than 4.

ask yourself... can A and B occur at the same time... that is, is there some number the player can roll which will satisfy both A and B?

Answer 16

oh my gosh, it has to be union... I already asked the other person if it was and he said no.

Answer 17

it's mutually exclusive, silly! you need to learn the definitions, understand what they mean and then learn to apply them.

You can do it!
