Answer:

C. 4

Step-by-step explanation:

Hi, the number of sample points is the sum of all attempts you executed during an experiment. Because the experiment proposes tossing a coin 4 times, then you have 4 sample points.

Attempt 1 = coin toss 1 = sample point 1

Attempt 2 = coin toss 2 = sample point 2

Attempt 3 = coin toss 3 = sample point 3

Attempt 4 = coin toss 4 = sample point 4

$\bf \textit{middle point of 2 points }\\ \quad \\

&x_1&y_1&x_2&y_2\\
% (a,b)
P&({{ 3}}\quad ,&{{ 5}})\quad 
% (c,d)
Q&({{ c}}\quad ,&{{ d}})
\end{array}\quad
% coordinates of midpoint 
\left(\cfrac{{{ x_2}} + {{ x_1}}}{2}\quad ,\quad \cfrac{{{ y_2}} + {{ y_1}}}{2} \right)=(-2,0)\\\\
-----------------------------\\\\
\left(\cfrac{{{ c}} + {{ 3}}}{2}\quad ,\quad \cfrac{{{ d}} + {{ 5}}}{2} \right)=(-2,0)M\implies 
\begin{cases}
\cfrac{c+3}{2}=-2\\\\
\cfrac{d+5}{2}=0
\end{cases}$

if you solve those equations for "c" and "d" respectively, you'd get, well the Q point of c,d
