Hint: sum of probabilities must be 1

What 😭

pseudo jetty Mar 18, 2024, 12:51 PM

#

0.12+0.5+0.2+P(M n N) = 1
P(M n N) = ?

zealous fiber Mar 18, 2024, 12:55 PM

#

0?

#

Wait waittt

#

Check this please

P(M) = 0.5
P(N) = 0.5
P(M ∩ N) = 0
P(M U N) = P(M) + P(N) - P(M ∩ N) = 0.5 + 0.5 - 0 = 1

P(M ∩ N^c) = P(M) = 0.5
P(M^c ∩ N) = P(N) = 0.5

It's wrong isn't it

pseudo jetty Mar 18, 2024, 1:35 PM

#

yes it's totally wrong
