Outcome:  "first coin lands heads up"  happened (1400+1250) times out of 
(1400+1250+1500+1050), so the relative frequency would be 

2650                                         2650
----------------------------------- = ----------- = 0.510 = desired relative frequency
(1400+1250+1500+1050)         5200
