Question

Given: P(A) = 0.45, P(B) = 0.25, P(AUB) = 0.7,

a) Determine P(A∩B)

b) Are A and B mutually exclusive? Explain

Answer 1

A) is that 0 the answer

Answer 2

B) it's mutally exclusive, because the two sets have no elements in common

Answer 3

P(AUB) =P(A) + P(B) - P(AnB)

Answer 4

ya

Answer 5

i got 0

Answer 6

use it to find P(AnB)

Answer 7

i did

Answer 8

u got 0?

Answer 9

i got 0 the result

Answer 10

good

Answer 11

right

Answer 12

if the sets are exclusive then
\[(A n B) = \phi \]

Answer 13

Since P(AnB) =0 it is mutually exclusive event

Answer 14

what about B

Answer 15

explain in B

Answer 16

Since P(AnB) =0 it is mutually exclusive event

Answer 17

B) it's mutally exclusive, because the two sets have no elements in common

Answer 18

right

Answer 19

yep

Answer 20

thnx

Answer 21

they might not be mutually exclusive

\[P(A\cap B)=0\] does not imply that \(A\cap B=\emptyset\)
