Students are chosen at random, one by one, from the original 28, until the student

Calculate the probability that this is the third student chosen



the probability that the 1st student does not have a grade 5 is -> 28/28 - 4-28 = 24/28

the probability that the second student does not have a grade 5 is --> 27/27 - 4/27 = 23/27

the probability that the third student HAS a grade 5 is -> 4/26

multiply them

u put that "cracked sin curve" ka symbol between the origin and the next point (all on Y axis) and then put the point above that as 400

something like the attached one

PS : I'm not sure on this one.

and yea...the lamps are connected in parallel or series?

my friend told me that it is used to make the image of a mirror straight and accurate...

The pins used for light experiments? 2 to 3 of them arranged on either side of the prism/glass block and later used to draw rays. TO my knowledge.

Two are used a object. A prism is placed in front of them. The image of the two pins are spotted from the other side and two more pins are arranged in a straight line as seen.

Title: Re: Latest maths notes at astarmathsandphysics.com
Post by: Ghost Of Highbury on May 04, 2010, 07:26:21 am
Reed switch is a glass tube containing two iron reeds sealed inside it.

If the iron is unmagnetized, there is a gap between the reeds and no current can flow. This is called a Normally Open Reed (NO)

If a magnet is brought near the reed switch, there is magnetic induction and the two reeds touch each other. Thus, the current can flow and the circuit is complete.

If an extra non-magnetic contact is added to the reed switch, it can be used as a NC (Normally closed) reed switch.

The current can flow until a magnet is brought near. When a magnet is brought near, one of the reed which is in contact with the non-magnetic contact attracts to the other reed and flow of current stops.

How can you connect only ONE voltmeter for TWO lamps?

a rule for parallel circuits that u should kno is that the p.d is not shared like the series circuit and that;s y u can u se only one voltmeter
