Question.

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

Three coins are tossed simultaneously 200 times with

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

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