A five card hand is dealt at random from a standard deck (52 cards). what is the probability that the hand contains exactly 2 red cards ?

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

answer: (x+2) (x+3) are the binomials for your question : )

10 - 8 = -2

  8 - 6 = -2

etc, so -2 is the common difference
