Question

two coins are tossed simultaneously 200 times and the following outcomesare recorded:
HH HT/TH TT
56 110 34
what is the empirical probability of occurrence of at least one head in the above case?

Answer 1

Answer:

Please read it carefully not clear

Step-by-step explanation:

Answer 2

0.83 or $\frac{83}{100}$

If the coins are tossed 200 times, the sample set for the outcome is 200.

It is given that we recorded two heads at the same time a total of 56 times. And a combination of heads and tails a total of 110 times.

The probability that at least one head occurs means that both the fact that a combination of heads and tails has occured as well as a combination of both coins are heads are acceptable.

Thus, the total outcomes of this is 56 + 110 = 166.

Thus, the probability of this happening =  $\frac{total outcomes for at least one head}{sample set for the outcomes}$

∴ Probability of getting at least one head = $\frac{166}{200}$

∴ Probability of getting at least one head = 0.83 or $\frac{83}{100}$
