Two events associated with a random experiment are said to be mutually exclusive, if both cannot occur together in the same trial. In the experiment of throwing a die, the events A = {1, 4} and B = {2, 5, 6} are mutually exclusive events. In the same experiment, the events A = ..

Thus, the Pauli's exclusion principle may also be stated as "An orbital can have maximum of two electrons and these two must have opposite spin". The maximum number of electrons in each main energy level can be predicted by extending this principle. The tabular column given below the vari..

Synthetic Elements Including Transuranics - Nuclear reactions involving the bombardment technique by different particles have been used to synthesise artificial elements such as Technetium, Astatine and Transuranium. (Z > 92) which follow uranium in the periodic table. The nuclear reactio..

AC = 7 cm, BD = 6 cm and the angle included by them is 60 o . (i) AC = 7 cm and draw its perpendicular bisector to get mid-point O. (ii) At O make COX = 60 o and produce it both ways. (iii) With O as centre and radius 3 cm cut OX at D and B. (iv) Join AB, BC, CD and AD. Then ABC..

The range for the above ungrouped data is 49 - 12 = 37. Normally it is desirable to divide the range into 6 to 10 classes. Consider the class 11 - 15. If a student scores 11 marks or 15 marks, he will be put in this class. For this class, 11 is the lower limit and 15 is the upper limit and both are..

. The blue-green algae among algae and the bacteria which were earlier placed in the group Thallophyta, were found to contain prokaryotic cells. All other algae, fungi, protozoans and multicellular animals were found to be composed of eukaryotic cells. Copeland suggested in 1966, the erection of a ..

Inclusive type of frequency distribution can be converted into exclusive type as in Table (..

The kingdom Mycota includes exclusively the fungi. The fungi are a group of organisms which has a plant body called thallus that may be unicellular or multicellular. They are achlorophyllous and non-vascular. Fungi represent another major group of decomposers along with some of ..

The meristematic tissue is formed exclusively by undifferentiated or embryonic cells. These cells, known as meristematic cells, are responsible for bringing about growth of the plant body due to their capacity to undergo continuous mitotic division..

(1) Mark class intervals on X-axis and frequencies on Y-axis. (2) The scales for both the axes need not be the same. (3) Class intervals must be exclusive. If the intervals are in inclusive form, convert them to the exclusive form. (4) Draw rectangles with class intervals as ba..
