Question

The following table shows the frequency of outcomes when two distinguishable coins were tossed 4000 times and the uppermost faces were observed.
Outcome HH HT TH TT
Frequency 1,100 950 1200 750

what is the relative frequency that the first coin lands with heads up?

Answer 1

$Relative\ frequency=\frac{frequency\ of\ a\ particular\ outcome}{total\ number\ of\ experiments}$
So in this case we get:
$R.Freq.=\frac{1100+950}{4000}$
which can be simplified.
