Question

He following table shows the frequency of outcomes when two distinguishable coins were tossed 5,200 times and the uppermost faces were observed. Outcome HH HT TH TT
Frequency 1,400 1,250 1,500 1,050
What is the relative frequency that the first coin lands with heads up

Answer 1

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
