Number of moves:
you are given a nxn square chessboard with one bishop and k number of obstacles placed on it. A bishop can go to different places in a single move. find the total no.of places that are possible for the bishop in a single move. Each square is referenced by a type describing the row, R, and column, C, where the square is located.
explanation: given N=6 K=2
bishop position 5 2
obstacle positions (2 2), (1 5)
the bishop can move in so o/p is 6
I/p:

- The number of accidents in a production facility has a Poisson distribution with a mean of 2.7 per month. For a given month, what is the probability that there will be more than three (3) accidents?
- The blood groups of 200 people are distributed as follows: 40 have type A blood, 75 have type B blood, 60 have type O blood, and 25 have type AB blood. If a person from any of the group is selected at random, what is the probability that this person has an O blood type? How about the AB blood type?
