(a)

The probability that drive to school in less than $\"\"$ minutes is $\"\"$ .

Where $\"\"$ is the probability density function for the time it takes you to drive to school.

The probability density function : $\"\"$ .

Using the probability density function, represent the above probability function in integral as $\"\"$ .

Thus, the integral function drive to school in less than $\"\"$ minutes is $\"\"$ , Where $\"\"$ is measured in minutes.

$\"\"$

(b)

The probability that it takes more than half an hour to get to school is $\"\"$ .

The integral function that it takes more than half an hour to get to school is $\"\"$ .

$\"\"$

(a) The integral function drive to school in less than $\"\"$ minutes is $\"\"$ ,

(b) The integral function to the probability that it takes more than half an hour to get to school is $\"\"$ .
