Shaquana is playing a board game. The probability that Shaquana will lose a turn on her next turn is 12. Which word or phrase describes the probability that Shaquana
will lose a turn?

Unlikely

Step-by-step explanation:

50/50 means that there is half a chance to loose a turn or 6/12 which is not the case.

Certain is definitely not correct as there is only 1/12 of a chance.

And impossible is not possible because it would have to be 0/12. There is still a chance to loose a turn with 1/12

the value of v.w= -12.

step-by-step explanation:

we are given three vector r,v and w as:

r = < 5, -5, -2> ; v = < 2, -8, -8> ; w = < -2, 6, -5>

we know that r,v and w could also be represented as:

r=5i-5j-2k

v=2i-8j-8k

and w= -2i+6j-5k

where i,j and k are the unit vectors of x,y and z-axis respectively.

also we know that it has the following property:

i.i=1 ; j.j=1; k.k=1

and i.=j.i=i.k=k.i=j.k=k.j=0

i.e. when we multiply two vectors or we find it's dot product we need to only multiply the components of x coordinates with each other; y with each other and z with each other.

hence, v.w= (2i-8j- -2i+6j-5k)

                  = 2×(-2)+(-8)×(6)+(-8)×(-5)

                  = -4-48+40

                  = -12

hence, v.w= -12

i think 1: 2
