Question

Let A and B be two mutually exclusive events of a sample space S. If P(A) = 0.4 and P(B) = 0.1, find the probability P( A u B)

Answer 1

and that A u B has a line over it

Answer 2

\[P(\overline{A\cup B})\]

Answer 3

oh how did you do that

Answer 4

yes thats what it should look like

Answer 5

P(\overline{A\cup B})

Answer 6

since they are mutually exclusive
P(AUB) = P(A) + P(B)

Answer 7

\[P(\overline{A \cup B} )\] nice!
and i always use n for intersection
i want to write the correct symbol for intersection how to do that

Answer 8

\cap

Answer 9

to find \[P(\overline{ A \cup B})=1-(P(A)+P(B))\]

Answer 10

\[\cap \]
:)

Answer 11

Look at that beautiful notation :)

Answer 12

so its just .5

Answer 13

i can do underline ;)
\[\underline{AuB}\]

Answer 14

yes casemac

Answer 15

\[\overbrace{P(A\cap B)}\]

Answer 16

;)

Answer 17

nice mustache :)

Answer 18

yes

Answer 19

o-o
\(\overbrace{U}\)

Answer 20

lol...nice

Answer 21

yes....
