Step-by-step explanation:
Arc length formula is
where x is radinas.
A semi circle has a radian measure of
The radius is half of the diameter, 12 so the radius is
So the arc length is
Area of semi circle is
where r is the radius.
Solve 2 2/3 x 3 3/5 using an area model of 4 squares.

Given:
The two way table.
To find:
The conditional probability of P(Drive to school | Senior).
Solution:
The conditional probability is defined as:
Using this formula, we get
...(i)
From the given two way table, we get
Drive to school and senior = 25
Senior = 25+5+5
= 35
Total = 2+25+3+13+20+2+25+5+5
= 100
Now,
Substituting these values in (i), we get
Therefore, the required conditional probability is 0.71.
