Answer 2

any ideas?

P(A) is the probability of A happening
P(A bar) is the probability of A not happening

these probabilities must sum to 1
that being said which statement is false?

Answer 3

P(A) + P(A bar) = 1

based on this equation, which choice out of the 4 options is false? you have to re-arrange the equation algebraically

Answer 4

P(A) + P(A bar) = 1

if you subtract P(A) from both sides you get

1 - P(A) = P(A bar)

if you go back to the first equation, subtract P(A bar) from both sides you get

1 - P(A bar) = P(A)

based on these results which equation cannot be derived from the starting equation?
