The following table shows the frequency of outcomes when two

The following table shows the frequency of outcomes when two distinguishable coins were tossed 4.800 times and the uppermost faces were observed

outcome: HH. HT. TH TT

frequency:1,300 1,150 1,400 950

what is the relative frequency that heads comes up at least once?

Heads comes up atleast once in the following events :

HH
HT
TH

So, total of 1300 + 1150 + 1400 = 3850 times

So, relative frequency becomes :

3850 / 4800

385 / 480

77/96 or 0.802083333333333 ---> ANSWER
