Answer:
-62
Step-by-step explanation:
Two functions are given to us , which are ,
We need to find , ( f • g )(8) . So ,
⇒ ( f • g) = - n ( n - 2 )
⇒ ( f • g) = -n² + 2
⇒ (f • g) = 2 - n²
==================================
<u>Subst</u><u>ituting</u><u> </u><u>n</u><u> </u><u>=</u><u> </u><u>8</u><u> </u><u>:</u><u>-</u>
⇒ ( f • g)(n) = 2 - n²
⇒ ( f • g)(8) = 2 - 8²
⇒ (f • g)(8) = 2 - 64
⇒ ( f • g)(8) = -62 .

8 can be simplified into 4 then 2 then 1

Answer: D. Getting at least 2 heads and Getting at least 2 tails
=========================================================
Explanation:
Choice A is not disjoint because "getting at least 1 tail" could have the sequence TTH. We see that we have two tails and exactly one head. So the events "getting exactly 1 head" and "Getting at least 1 tail" are possible to occur at the same time; therefore, they aren't disjoint events. Disjoint events are two events that cannot occur simultaneously. An example would be flipping heads and tails on the same coin at the same time.
Choice B is also not disjoint. We could have the sequence THT, which has at least one head and at least one tail. "At least" means that amount or more.
Choice C is also not disjoint. We could have the sequence HTT. This has exactly one head and at least two tails.
Choice D is the only thing left. It must be the answer. It is not possible to get 2 heads and 2 tails when Roger only flips the coin 3 times. He would need to flip the coin at least 4 times for this to happen. The portions "at least" don't even need to be considered. So this shows how choice D is disjoint.
