Answer:
Step-by-step explanation:
For this case we assume that the probability of obtain a head is 1/2
We are conducting the experiment 3 times. And we want the probability that exactly the same number of tosses will be required for each of the 3 performances.
We can model the situation like this. Let the number of tosses used in the performance, for this case
And the distribution for would be a negative binomial with the following mass function:
Now we need to assume that the 3 performaces are independent from each other and we want this:
And we can since we have the mass function we can replace:
And as we can see we have a geamotric series and we can find the probability like this:
