Answer:

<h2>The answer is 0.008789.</h2>

Step-by-step explanation:

The probability of getting a head or tail in a toss is $\frac{1}{2}$ .

It is given that in the 6th toss, the outcome should be head.

Rather than the 6th toss, there are 9 tosses. From these 9 tosses 1 toss can be selected in 9 ways.

Hence, the probability is $9\times\frac{1}{2^{10}}$ = 0.008789.
