Question.

Three coins are tossed simultaneously 200 times with the following frequencies of different outcomes

If the three coins are simultaneously tossed again, compute the probability of 2 heads coming up.

Solution:

Number of times 2 heads come up = 72

Total number of times the coins were tossed = 200

$P(2$ heads will come up $)=\frac{\text { Number of times } 2 \text { heads come up }}{\text { Total number of times the coins were tossed }}$

$=\frac{72}{200}=\frac{9}{25}$
