Answer:
80 Trains
Step-by-step explanation:
Number of Trains Late = 3
Number of Trains on Time = 16
Total Number of Trains = 16+3=19
Relative Frequency = Number of Success/Number of Experimental Trials
Relative Frequency of a Train being on Time[tex]=\dfrac{16}{19}[/tex]
In experimental probability, we can use the relative frequency of an event in the experiment to predict for an increased number of trials.
Expected Number of Outcome = Relative Frequency of the Event X Total Number of Trials
In this case, the Total Number of Trials = 95
Number of Trains expected to be early [tex]=\dfrac{16}{19} X 95 = 80[/tex]
