Answer: 1/70
Step-by-step explanation:
This is a question that can also be interpreted as what is the probability of having the first number of a phone number to be 8 and the last number of the phone number to also be 8. This answer gives the fraction of the phone numbers that starts with 8 and end with 8.
Since three numbers (0,1,2) cannot start a phone number and we are left to pick from 7 numbers,
then the probability of figure "8" starting phone number = 1/7
Since all 10 numbers can possibly end a phone number,
then the probability of having figure "8" as the last digit of a phone number = 1/10
Hence probability of having "8" as the first and last digit of a phone number = fraction of total telephone numbers that begin with digit 8 and end with digit 8 = 1/7 × 1/10 = 1/70.

Step-by-step explanation:
Riding time after lunch = 41.
Riding time before lunch = 5 * 41 - 1
5 * 41 - 1 =
= 205 - 1 =
= 204
It means Javier rode his bike for 204 minutes (3 hours and 24 minutes) before lunch.
You need to make sure that you are not dividing by zero
so y - 1 = 0
y = 1
