Three coins are tossed simultaneously 200 times with the following frequencies of different outcomes:
Outcome3 heads2 heads1 heads0 head
Frequency23727728
If the three coins are simultaneously tossed again, compute the probability of 2 heads coming up.


Answer :

Number of times 2 heads come up = 72
Total number Of times the coins were tossed = 200

\(P = \frac{Number of times 2 heads come up}{Total number of times the coins were tossed}\)
\(P = \frac{72}{200} = \frac{9}{25}\)

Therefore, the probability of 2 heads coming up is \(\frac{9}{25}\).
