The inventor of the chess board suggested a reward of one grain of wheat for the first square, 2 grains for the second, 4 grains for the third and so on, doubling the amount of the grains for subsequent squares. How many grains would have to be given to the inventor? (There are 64 squares in the chess board).

Three squares of Chess board are selected at random. Find the probability of getting 2 squares of one colour and other of a different colour.

A chess board contains 64 equal squares and the area of each square is 6. 25\ c m^2 . A border round the board is 2 cm wide. Find the length of the side of the chess board.

Keith modeled the growth over several hundred years of a tree population by estimating the number of the trees’ pollen grains per square centimeter that were deposited each year within layers of a lake’s sediment. He estimated there were 310 pollen grains per square centimeter the first year the grains were deposited, with a 1% annual increase in the number of grains per square centimeter thereafter. Which of the following functions models P(t), the number of pollen grains per square centimeter t years after the first year the grains were deposited?

A corn cob (see in figure), shaped somewhat like a cone, has the radius of its broadest end as 2.1 cm and length as 20cm. If each 1\ c m^2 of the surface of the cob carries an average of four grains, find how many grains you would find on the entire cob?

How much time (in hours) would it take to distribute one Avogadro number of wheat grains if 10^(20) grains are distributed each second?

If two of the 64 squares are chosen at random on a chess board, the probability that they have a side in common is

When a red grain variety of wheat is crossed with another white grain vartiety F_(1) hybrid is produced. On selfing of this F_(1)- hybrid, how many offsprings of F_(2)- generation resemble phenotypically to it's parents (let grain colour of wheat controlled by three gene pairs )
