Answer:
see explanation
Step-by-step explanation:
the equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h. k) are the coordinates of the centre and r is the radius
here (h, k ) = (- 6.2, 5.8 ) and r = , hence
(x + 6.2)² + (y - 5.8)² = ( )²
(x + 6.2)² + (y - 5.8)² =
Answer:
0.14% probability of a person guessing the right combination
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
The order in which the numbers are selected is important. For example, 1,3,2 is a different combination than 3,1,2. So we use the permutations formula to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
Desired outcomes:
One right combination, so
Total outcomes:
10 numbers from a set of 3. So
What is the probability of a person guessing the right combination?
0.14% probability of a person guessing the right combination
