Answer:
The total number of samples that give this outcome is 5.
Step-by-step explanation:
Since Y takes values in {0,1,2,3}, For us to have that 
implies that all of them are zero but one. The one that is non-zero necessarily is equal to 1. To calculate the number of samples that give this outcome is equivalent to counting the total number of ways in which we can pick the i-index such that 
. Note that in this case we can either choose Y1 to be 1, Y2 to be 1 and so on. So, the total number of samples that give this outcome is 5.
Clean up the equation with x first and x=12.
Substitute this value in to the other equation to solve for y.
You should get a solution of (12,-8)
It is one fourth of twenty so therefor 5 is 25% of 20
Answer:
195
Step-by-step explanation:
So -79 + x = 116
then x = 116 + 79 = 195
Let x represent his daughter age
Then the expression: 5x - x = 36
Solve for x: 4x = 36
Then x = 36/4 = 8
The daughter is 8 years old
Jamari is 40 years old
