To do this multiply 1 by 4, then 3 by 5. 4 over 15 is your answer.
Hope this helps, have a great!!
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:
360
Step-by-step explanation:
All the angles of a polygon add up to 360, thats kinda just how it is haha
