Answer:
Option 2 is true.
Step-by-step explanation:
Th sum of probabilities of two complementary events is one, which implies
P(A) + P(B) = 1
So,
P(B) = 1 - P(A)
11
2 3/4 times 4 equals 11
no
Just plug it in
-4(4) + 3(1) = 2
-16 + 3 = 2
-13 = 2
Without even solving the second equation, the answer is no because -13 does not equal 2
18
