He is wrong by him thinking the simple equation which is 1000/2 from the 2 sided coin but in reality you could either get more heads or tails/less heads or less tails. You can’t get an exact number from the chances of basically luck I’d assume

Help please idk what im doing wrong
Musya8 [376]
From what I can see, you are on the right track.

one thing you could have done is combine like terms.
{10}^{2}  -  {3}^{2}  =  {7}^{2}

Now just take the square root of 7 squared. That takes out the squared making your answer 7 or G.

You were on the right track, you just skipped a step.

hope this helped!
