we have
p (a) =2/5 p(b)=1/4 ( a and b=1/25
Remember that
we know that for two independent events A,B.
⇒ P(A∩B)=P(A)*P(B)
we have
P(A)=2/5 and P(B)=1/4
so
P(A∩B)=(2/5)*(1/4)=2/20=1/10
that means
<h2>events are dependent</h2>
The answer to 10 is A......the answer to 11 is D...the answer to 12 is
4x4=16. So think of it like this now..
3x-16=65
Add 16 in each side and you get 3x=81. Divide 3 with 81 and should be 27, or x=27.
Then you check it by putting in the #'s
3(27)-4(4)=65
81-16=65
65=65 ✔️
