Answer:

1) 
2) 
We can find the individual probabilities and we got:



And the sum of the 3 values 0.6923+0.2307+0.0770= 1 so then we satisfy all the conditions and we can conclude that f(x) is a probability distribution.



Step-by-step explanation:
For this case we have the following density function:

In order to satisfty that this function is a probability mass function we need to check two conditions:
1) 
2) 
We can find the individual probabilities and we got:



And the sum of the 3 values 0.6923+0.2307+0.0770= 1 so then we satisfy all the conditions and we can conclude that f(x) is a probability distribution.
And if we want to find the following probabilities:



Answer:
1 is a, 2 is c, 3 is a, 4 is b, 5 is c, 6 is a, 7is a,8 is b, 9 is c
Step-by-step explanation:
There are no real values for log of 0 or negatives.
So the answer is B
Let A = {Dirk, Johan, Frans, Sarie}, B = {Frans, Sarie, Tina, Klaas, Henrika}, C = {Hans, Frans}. Find the number indicated.

Thank you for posting your question here at brainly. I assume the question should be "<span>Find the number indicated". below is the answers:
</span>B U C means B union C which combines them:
<span>{Frans, Sarie, Tina, Klaas, Henrika, Hans} note that there is no need to write Frans twice. </span>
<span>∩ means intersection which is only what the two sets have in common, in this case: </span>
<span>{Frans, Sarie} </span>
<span>the number is 2. </span>
Answer:
Alvin is 47 and Elga is 35
