Detailed Solution

Given two coins are tossed 1000 times and the outcomes are recorded as under.

Frequency of getting at most 1 head is,
= frequency of getting 0 head + frequency of getting 1 head
= 194 + 540
= 734
Number of times at most 1 head appeared = 734
And, total number of outcome = 1000
The probability of an event =

\frac{Number of favorable outcomes}{Total number of outcomes}

Now, the probability of getting at most one head is,

= Number of times at most 1 head appeared Total number of outcomes = 7341000

= 367500

The probability is

367500

.
Hence, option 3 is correct.
