Given:

Three coins are tossed simultaneously 200 times.

The three coins are simultaneously tossed again.

To do:

We have to find the probability of 2 heads coming up.

Solution:

Total number of outcomes $=200$

Number of events in which two heads come up $=72$

We know that,

Probability of an event=$ \frac{\text{ Number of favourable outcomes }}{\text { Total number of outcomes }}$

Therefore,

Probability of getting two heads $=\frac{72}{200}$

$=0.36$

This implies,

The probability of 2 heads coming up is $0.36$.
