Third option is the right choice.
Step-by-step explanation:
The intersection point of both lines is .
Area of triangle
This represents the height of the triangle.
So, the y-coordinate of C, will be y-coordinate of point of intersection plus height of triangle.
y = 5+2 = 7

The probability that exactly 6 of 8 adult use their smartphones in meetings or classes is 0.147 or 14.7% .
The complete question is
Assume that when adults with smartphones are randomly selected, 54% use them in meetings or classes (based on data from an LG Smartphone survey). If 8 adult smartphone users are randomly selected, find the probability that exactly 6 of them use their smartphones in meetings or classes.
<h3>What is Probability ?</h3>Probability is the measure of likeliness of an event to happen.
The probability given is
p = 54% = 0.54
n =8
r = 6
The binomial Probability is given by
The probability that exactly 6 people use smartphones in a class of 8 student is given by
Here q represents the complement
q = 1 -p
q = 1-0.54 = 0.46
Therefore The probability that exactly 6 of 8 adult use their smartphones in meetings or classes is 0.147 or 14.7% .
