If his first class in the morning starts at 8:00 am, and he leaves the dormitory at 7:45 am daily, the chance that he would be late for his first class is 0.9878 ((expressed in four decimal places). The length of time which is the slowest 15 % of the trips is 1985 minutes (expressed in two decimal places). The probability that 2 of the next 3 trips will take at least 1/2 hr is 0.01 (expressed in two decimal places).

S1
When the face-to-face class resumes after the pandemic, a DATAENG student commutes daily from his dormitory to DLSU and the average time for a one-way
trip is 24 minutes, with a standard deviation of 4 minutes. Suppose that the distribution of the trip times is normally distributed.
If his first class in the morning starts at 8:00 am, and he leaves the dormitory at 7:45 am daily, the chance that he would be late for his first class is
0.9878
((expressed in four decimal places).
The length of time which is the slowest 15 % of the trips is 19.85
minutes (expressed in two decimal places).
The probability that 2 of the next 3 trips will take at least 1/2 hr is 001
(expressed in two decimal places).
