Benford's law states that in a very large variety of real-life data sets, the first digit approximately follows a particular dis
tribution with about a 30% chance of a 1, an 18% chance of a 2 and in general P(D=j)=log10(j+1/j), for j in {1,2,23,...,9}, where D is the first digit of a randomly chosen element. Check that this is a valid PMF (using properties f logs, not with a calculator).

See the picture for all detail, I have done it by hand.
Few important steps;
-Take the first derivative
-Put it equal to zero
-you get the x value which is equal to 11
-Now for the check that x=11 is the least value or not, take the second derivative
-As, the 2nd derivative is positive so it is the least value
As x=0 in 1964 add 11 to it so at x=11 we get 1975 so in this year car have least value

Step-by-step explanation:
okay relax dw it's all good
1. B : just count one whole pizza and the addition three out of 8
2. B addition question : 2+13+1+4+2 break it up
2+13=15+1=16+4=20+2=22
3. multiply 9 and 5. do the grouping thing if you need help
4. possible combinations can be done by drawing a big tree graph. I have attached an example above in image. count along each branch. there are 8 combinations.
5. this is called a 90° angle
