Answer:
So the probability is P=0.00256.
Step-by-step explanation:
We have 26 letters, so the probability that the first letter in the name is the same is 1/26.
The probability that the second letter in the name is the same is 1/26 and the probability that the third letter in the name is the same is 1/26.
Out of ten people we choose 2.
So the probability is:
So the probability is P=0.00256.
The answer is:
The second distance () is equal to 7.5 feet.
Since we are given two forces acting at distance, torque will be created. We are given two forces and one distance, so, to calculate the other distance required to balance the system (solve this fulcrum problem), we need to write the following equation:
Where,
We are given,
So, substituting and calculating, we have:
Hence, the second distance () is equal to 7.5 feet.
It's a logical solution since the second force is twice the first force and it means that the second distance must be equal to half the first distance in order to maintain the equilibrium condition.
Have a nice day!
