If the coin is flipped 140 times, how many times would you predict the coin lands on heads

The theoretical probability of a coin flip is 1/2, meaning half the time the coin will land on heads and half the time the coin will land on tails. If the coin is flipped 140 times, half of those flips should be heads. So, the prediction would be 140 * 1/2 = 70

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
