Answer:
2.5
Step-by-step explanation:
16-13.50
There are 2 answers: Choice 1, Choice 4
=======================================
Why is this? Because we use the rule
P(A & B) = P(A) * P(B)
which only works if events A and B are independent
----
For the first answer choice,
P(A) * P(B) = 0.6*0.4 = 0.24 = P(A & B)
so that matches.
The same applies to the fourth answer choice as well
P(A) * P(B) = 0.3*0.2= 0.06 = P(A & B)
----
The other answer choices don't match up.
The second answer choice has
P(A) * P(B) = 0.3*0.4 = 0.12 but that doesn't match with the 0.70 given
Similarly for the third answer choice,
P(A) * P(B) = 0.5*0.1 = 0.05 which doesn't match with the 0.60

Answer:
c=-6
Step-by-step explanation:
I used a calculator and paper and a pencil d---------b yeah :D yr welcome
Ok, so you would want to simplify both sides of the equation
(-1/3)(-12) + (1/3)(-12c)=-20 (here you distribute)
4+4c=-20
Then, subtract 4 from both sides
4c+4-4=-20-4
4c=-24
Then divide both sides by 4
4c/4=-24/4
c=-6
