Question 384436
4 heads 
4 tails 

Each is 50/50 so being tails 50% of the time and heads 50% of the time.

50% + 50% = 100% tails that 2 of the 4 
50% + 50% = 100% heads of 2 of the 4 
with 4 coins tossed fairly there is 100% chance of 2 being heads and 100% chance of 2 being tails. 2/4 2/4   of each evenly. 

2/4 tails 2/4 heads
