Explanation for the correct options:
Step 1. Find the total number of ways :
Given that and toss a fair coin each simultaneously times.
For each toss, there will be choices.
Choice: gets head, gets head
Choice: gets tail, gets head
Choice: gets head, gets tail
Choice: gets tail, gets tail.
Therefore, the total number of ways
Step 2. Find the required probability :
Out of four choices, choice is not favorable.
Therefore, the favorable number of ways
Hence, the required probability
Hence, option(A) is the correct answer.
