$\sf\fbox\red{Answer:-}$

$\frac{9}{25}$

Step-by-step explanation:

A = event that 2 heads come up while tossing 3 coins simultaneously.

Number of times 2 heads come up =72 ....given

Total number of times the coins were tossed =200 ...given

Probability =

$\frac{number \: of \: times \: 2 \: heads \: come \: up}{total \: number \: of \: times \: the \: coins \: were \: tossed }$

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