Non Leap year has 365 days

365days = 52 weeks + 1 day

Since, There are 52 weeks in a non leap year,

Therefore, There are minimum 52 Tuesday.

Now 1 additional day can be :

{ M , T , W , Th , F , Sa , S }
n(S) = 7

Probability of getting 53 Tuesday = Probability of getting Tuesday as extra day

So, P = 1/7

Einstein was being taught subjects like history which he had no interest in. He did not like memorising dates. He was against learning facts and dates, because that only is not education.

1. Ur was one of the earliest cities to have been excavated in Mesopotamia. Narrow winding streets indicate that wheeled carts could not have reached many of the houses.

1. After 2000 BCE the royal capital of Mari flourished. Mari stands not on the southern plain with its highly productive agriculture but much further upstream on the Euphrates.  Here agriculture and animal rearing were carried out close to each other in this region.
2. Herders need to exchange young animals,cheese, leather and meat in return for grain,metal tools, etc., and the manure of a penned flock is also of great use to a farmer. Yet, at the same time, there may be conflict between the regions.

8. Thus, although the kingdom of Mari was not militarily strong, but it was exceptionally prosperous.
