$($Simulation of tossing a biased coin$)$ Simulate the tossing of a biased coin whose tails is

three times more likely to be showing than its heads, until the gap between the number of

heads and that of tails reaches $15.$ Print out the number of tosses needed. Then use a for$-$loop

to repeat the simulation ten times. Your output should look like

Note. Simply write your code in a single code block. You do not need to write a function

for this.
