The following table shows the frequency of outcomes when two distinquishable coins were tossed 6,000 times. What is the estimated probability that heads comes up at least once?



Outcomes HH HT TH TT
Frequency 1,501 1,505 1,502 1,492

a) 0.5002
b) 0.7513
c) 0.0008
d) 0.2508
e) 0.2503

-
the estimated probability that heads comes up at least once - in how many tosses?

If you mean in a single toss of the two coins, its (1,501 + 1,505 + 1,502)/6000 = 0.7513, answer b)

-
you have at least one head in HH HT and TH, add those numbers together and divide by total number of tosses.

4508/6000 = 0.7513
