Hal has 20 pieces of candy in a bag: 12 mint sticks, 5 jelly treats, and 3 fruit tart chews. if he eats one piece every 8 minutes, what is the probability his first two pieces will both be mint sticks?

Step-by-step explanation:

Given : Number of pieces of candy in the bag =20

Number of pieces of mint sticks =12

If he eats one piece every 8 minutes, then the number of ways that he eats mint sticks =

The total number of ways that he eats any two pieces of candies=

Now, the probability his first two pieces will both be mint sticks :-

Hence, the probability his first two pieces will both be mint sticks =  

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
