So the numbers on the credit card can start with any single-digit number
So it could start with;
0
1
2
3
4
5
6
7
8
Or 9
We are looking for the odds of it starting with a 7
There is only one 7, so the numerator is 1
There are then nine other possible numbers it could be, and counting the number 7, there is a total of ten different possibilities, so 10 is the denominator
So the odds of the card starting with a 7 is
1/10

V1 :V2= 250 : 686 =125 : 343 , Volume ratio= 125: 343
r1: r2 = ∛125 : ∛243 = 5 : 7 , Scale factor =5:7
S1:S2 = 5² : 7² = 35 : 49, Surface area ratio =35 : 49
Scale factor =5:7
Surface area ratio =35 : 49
Volume ratio= 125: 343
