If events a and b are independent, what must be true? p(a|b) =  p(b)p(a|b) =  p(a)p(a) =  p(b)  p(a|b) =  p(b|a)

We are given that

events A and B are independent

so,

P(A∩B)=P(A)*P(B)

we know that

P(A|B)=(P(A∩B))/(P(B))

we have

P(A∩B)=P(A)*P(B)

we can plug it

P(A|B)

P(A|B)

so,

option-B..........Answer

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
