In a shipment of 2,500 video games, 97 are defective. if a person buys two games, what is the probability that neither is defective?

There is a 92.39% probability that neither is defective.

Step-by-step explanation:

Initially, there are 2500 video games, of which 97 are defective and 2500-97 = 2403 are not defective.

So the probability that the first video game bought is not defective is 2403/2500.

Now there are 2499 videogames, of which 2402 are not defective. So the probability that the second videogame bought is not defective when the first one isn't is 2402/2499.

What is the probability that neither is defective?

There is a 92.39% probability that neither is defective.

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down

the first one, all those points on the line just make a strait line.
