Question

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

Outcome	$3$ heads	$2$ heads	$1$ head	No head
Frequency	$23$	$72$	$77$	$28$

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

Answer 1

Number of times $2$ heads come up = $72$

Total number of times the coins were tossed = $200$

Probability of $2$ heads coming up = $\frac{\text{Favorable Outcomes}}{\text{Total number of outcome}}=\frac{72}{200}=0.36$
