Solution

The correct option is A 0.425
We know, for an event E,
P(E) = $\frac{Number of trials in which the event happened}{Total number of trials}$

Here, the event E is 1 head appearing, which happens 85 times.
Given, total number of trials(or tosses) is 200.
Therefore,
P(E) = $\frac{85}{200}$ = 0.425
