Binomial distribution
Binomial distribution
pdf (probability distribution function ) of the binomial distribution is
Mean of the binomial distribution = np
Variance of the binomial distribution = npq
mgf (moment generating function of the binomial distribution) is [q + p (e^t) ] ^n
derivation of mean and variance of binomial distribution :derivation of mean and variance of binomial distribution
derivation of mgf of binomial distribution and deduction of mean and variance from the mgf:
mgf of the binomial distribution
derivation of mode of binomial distribution : mode of binomial distribution

journey from trivandrum to karaikudi
journey from trivandrum to karaikudi
The route was along
Trivandrum - Martandam - Nagercoil - Thirunelveli -Madurai - Melur - Karaikudi
around 400 km. NH 47 and then NH 7
The road from Trivandrum to Nagercoil was the worst in terms of congestion and it took around 2 hours. There was also a small strip of road at Martandam near the bridge which was full of potholes (This could be avoided by taking a side road ).
After that there was a 4-lane road (2-lanes each for either direction) for most of the route to Madurai, which bypassed most of the small towns. But there is some construction going on at some parts of the road. So there is diversion at some parts
and you might also see some vehicles, (some of which are part of the road works ) coming at you from the opposite direction in your lane due to these diversions.
There was also some construction work near Thirunelveli which caused some traffic block for around 20 minutes.
Earlier you would buy sweets like thenkuzhal(the sweet, not the murukku) , aluva etc at thirunelveli. You could buy small cucumbers, pomegranite at various small towns, but most of these are not possible on the new 4-lane road unless you went out of the way along the exit to visit those towns. You could go to the new bus stand at Thirunelveli and buy the sweets from the shops inside the bus stand.
Earlier it was a headache to go through Madurai due to the traffic, but now there is a bypass [ There is a right angle turn towards the right with a (unmarked ?)bump leading to the bypass ] There is a toll of Rs. 35 /-(depending on where you are going) and around four toll gates where you have to show your receipt. There is also some traffic on the bypass since it is connected to the city at some points.
After that the journey is along the 4-lane road for some more distance. You can bypass Melur and take the cut for Karaikudi from the 4-lane road if you know the correct cut [ a vendor of tender coconuts on the roadside told me about that in terms of the approximate distance km ]
After that the road is the usual 2-lane(1-lane each for either direction)with some tamarind trees on the sides.
There is a lot more traffic in Karaikudi. Traffic signals have been installed. A traffic warden shouts at people who have not parked properly through a public address system. Road dividers have come up on the main road.

finance
There seems to be a type of people who live on credit. They buy the latest items like the newest model cars, tv' s etc and do not care if they are not able to afford the items. They would just charge it to their cards or take out a new loan. This was not common in India in the 70's . But with the advent of liberalisation and entry of foreign banks, this type of people are becoming common in india, especially among those in the IT field.
Till the recent recession in the USA and the corresponding slowdown in India, banks were competing with each other in issuing credit cards. Some people would just use a credit card to waste money on the latest and costliest stuff and would then just go about paying the minimum possible on their credit card debt per month.Some people do not even understand that even a single mistake on their part or a late/ missed payment might sometimes just blow up the interest rates on their credit card debt. They sometimes fail to understand that there is no such thing as a free lunch with regard to credit card companies.
Some of the younger generation seem to have forgotten the value of frugality and the concept of living within their means.
When you use credit cards , you do not have the same feeling / care as when you count out currency notes. Also some credit card companies entice you with offers of cash back offers, free gifts etc if you buy a lot of items using your credit card. All of this sometimes leads to overspending.
