Sveta_85 [38]

Answer:0.017578

Step-by-step explanation:

Given

Nine coins are flipped

So the probability of getting a tail is $\frac{1}{2}$

Because on flipping a coin could either yield Head or tail

so getting a tail on nine trails is $\frac{1}{2^9}$

but this tail can come on first coin or second or third ....

So there are 9 possible ways

So probability of getting a tail on flipping nine coin is $9\times \frac{1}{2^9}$

$=\frac{9}{2^9}=0.017578$
