The answer is 80 and 8
. 8x10=80
80-8=72
The next number would be 19.
Each number adds one more each time.
For example, 4+0=4, 4+1=5, 5+2=7, 7+3=10, 10+4=14, 14+5=19
Hopefully this makes sense, its kind of hard to explain.
Hope this helps :)
No. The answer would be less than one because 80 is less than 813.
The real answer would be around 0.1
Answer:
P(she selects the route of four specific capitals) = 1 in 2,686,320 or 3.72 x 10⁻⁷
Step-by-step explanation:
Assuming that the order at which she visits each of the four cities matters, the number of possible routes is the permutation of choosing 4 out of 42 capitals:
![n=\frac{42!}{(42-4)!}\\n=42*41*40*39\\n=2,686,320\ ways](https://tex.z-dn.net/?f=n%3D%5Cfrac%7B42%21%7D%7B%2842-4%29%21%7D%5C%5Cn%3D42%2A41%2A40%2A39%5C%5Cn%3D2%2C686%2C320%5C%20ways)
Therefore, the probability that she selects the route of four specific capitals is 1 in 2,686,320 or 3.72 x 10⁻⁷
