Step-by-step explanation:
Let X the random variable that represent the variable of interest of a population, and for this case we know the distribution for X is given by:
Where
and
We are interested on this probability
We can find the individual probabilities. We can use the z score formula given by:
If we apply this formula to our probability we got this:
And if we add the two values we got 0.00135+0.00135 = 0.0027 and in % would be 0.27% and rounded would be 0.3 %
d. 0.3%

Answer:
(-5,-1)
Step-by-step explanation:
u = ((-7-3),(5-9))
u = (-10,-4)
v = ((6-1),-1-(-4))
v = (5,3)
u + v = (-10,-4)+(5,3)
u + V = (-5,-1)
