(b) 0.01 or 1%
Step-by-step explanation:
Since there are 10 possible numeric digits (from 0 to 9), and there is only one correct digit, there is a 1 in 10 change of getting each digit right.
The probability that if you forget your PIN, then you can guess the correct sequence
(a) at random:
![P=(\frac{1}{10})^4=0.0001=0.01\%](https://tex.z-dn.net/?f=P%3D%28%5Cfrac%7B1%7D%7B10%7D%29%5E4%3D0.0001%3D0.01%5C%25)
(b) when you recall the first two digits.
![P=(\frac{1}{10})^2=0.01=1\%](https://tex.z-dn.net/?f=P%3D%28%5Cfrac%7B1%7D%7B10%7D%29%5E2%3D0.01%3D1%5C%25)
Answer:
No
Step-by-step explanation:
For the adults:
$12 times the 14 adults which is: $168
Then for the kids:
$5 times the 9 kids which is: $45

$168 plus the $45 equals $213
A(14)+b(5)=c
