<span>This is correct. Data visualisation is done through the creation of graphs, which are simply visual representations of data that show relationships between variables. Bar graphs are a particular type of graph. Others include scatter graphs, line graphs and pie charts.</span>
Answer:

When squaring a fraction, square both numerator AND denominator
Step-by-step explanation:
Given that,
a)
X ~ Bernoulli
and Y ~ Bernoulli 
X + Y = Z
The possible value for Z are Z = 0 when X = 0 and Y = 0
and Z = 1 when X = 0 and Y = 1 or when X = 1 and Y = 0
If X and Y can not be both equal to 1 , then the probability mass function of the random variable Z takes on the value of 0 for any value of Z other than 0 and 1,
Therefore Z is a Bernoulli random variable
b)
If X and Y can not be both equal to 1
then,
or 
and 

c)
If both X = 1 and Y = 1 then Z = 2
The possible values of the random variable Z are 0, 1 and 2.
since a Bernoulli variable should be take on only values 0 and 1 the random variable Z does not have Bernoulli distribution
I think this the correct solution. but please correct me if I'm wrong
