Which of the following pairs of events are independent? Select all that apply.
A
Draw a 2 of clubs from a standard deck of 52 cards, keep it, then draw a 2 of diamonds.
B. Draw a 3 of spades from a standard deck of 52 cards, replace it, then draw a 5 of hearts,
C. Roll a number cube. Then roll again if the first roll is a 6.
D. Roll a 2 on a number cube and spin a 3 on a spinner.
E
Events A and B, where P(A) = 0.4, P(B) = 0.2, and P(A and B) = 0.8.
E
Events A and B, where P(A) = 0.1, P(B) = 0.5, and P(A and B) = 0.05.

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

my guess would be b and d, but i didn’t actually get out the pen and paper. lol
