Straightforward probability

Probability Level 1

I flip 3 coins.

Is the following statement correct?

Because 3 is triple 1, the chance that I get 1 head is triple the chance that I get three heads as I need three times more luck to get three heads.

Yes No

Even though the chance is correct the logic is incorrect; for example if we take 3 , 2 3,2 the chance that I get 3 heads is triple the chance that I get 2 heads, not 3/2 which contradicts the logic in the statement above.
