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:
Answer:
Step-by-step explanation:
Equation is below
Step 1
(7)^8(7)^0 simplifying
Step 2
(7)^8(7)^0 multiply 7
(5764801)(1)
Step 3
(5764801)(1) Multiply 5764801 by 1
5764801
Answer
5764801

Answer:
13, 15, 17
Explanation:
Consider three consecutive odd integers <span><span>(2n−1)</span>,<span>(2n+1)</span>,<span>(2n+3)</span></span>
Where n is Integer?
If the sum of these odd integers is 45,
Then: <span><span>(2n−1)</span>+<span>(2n+1)</span>+<span>(2n+3)</span>=45</span>
<span>6n+3=45</span>
<span>6n=42</span>
<span>n=7</span>
Substituting <span>n=7</span> into <span><span>(2n−1)</span>,<span>(2n+1)</span>,<span>(2n+3)</span></span>
Gives 13, 15, 17
To check: <span>13+15+17=<span>45</span></span>
