For this problem, assume that Pr[A ∪B] = 0.3 and Pr[A] = 0.2.

(1) What is Pr[B] if A and B are independent events?

Question

For this problem, assume that Pr[A ∪B] = 0.3 and Pr[A] = 0.2.

(1) What is Pr[B] if A and B are independent events?

anonymous · Answer

please help

anonymous · Answer

well if the union of the two is .3 and they are independent events than the union is just pr(A) + pr(B)

anonymous · Answer

.5 is wrong

anonymous · Answer

.1....
.3-.2 is = to .1...not .5.

anonymous · Answer

thats the answer for the disjoint one

anonymous · Answer

we need to find the independent

anonymous · Answer

no

anonymous · Answer

them being independent means they don't depend on each other. disjoint and independent are the same thing

anonymous · Answer

yes i have a thing for my homework you type in the answer and it tells you if its right or wrong .1 is wrong

anonymous · Answer

they dont' depend on each other
alright well. then forget it.

anonymous · Answer

so you don't know how to do it?

anonymous · Answer

apparently not. wait for someone else to reply or post in statistics

anonymous · Answer

there is no stats

anonymous · Answer

yes there is, i'm on it..

anonymous · Answer

its just called stats? i can't find it

anonymous · Answer

no. statistics. i say stats for short. basically for independent events. you would need to know the intersection of the events to find out B or vice versa
