Three movie tickets cost $19.50. how much will it cost for 5 movie tickets

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

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
