After single flip we would expect the cumulative proportion to be the closest to 1/2.

Cumulative proportion is defined as the division of favorable number of outcomes to the total number of outcomes.When we flip a coin then the coin has two choices either it will come as tail or it will come as head.Its a fair choice and we don't have any control on the outcome.

So,total number of outcomes are =2 which are Head and Tail.

Favorable outcome is =1 either it will be head or tail.

So,cumulative proportion =number of favorable outcome/Total number of outcome

=>cumulative proportion=1/2=0.5

Here we can see that on single flipping we can get a cumulative proportion close to 0.5.

Hence, single flip of coin is required.
