For this you will have to make a tree diagram
it will be so much easier although there is a way to do it
probability of getting heads is = 1/2 there for 10 tosses its (1/20)^10

=47.8888 when you round it up you can get get about 48 then you estimate to about 50.
B I think. Not 100% sure tho
Answer:
The point
is not a solution of the system of inequalities
Step-by-step explanation:
we have
-----> inequality A
-----> inequality B
we know that
If a ordered pair is a solution of the system of inequalities
then
the ordered pair must be satisfy the inequalities of the system
Verify
For 
substitute the value of x and the value of y in the inequalkity A and in the inequality B
Inequality A

-------> is not true
therefore
The point
is not a solution of the system of inequalities
