Roman is playing a game in which he draws cards from a standard 52-card deck. Roman draws one card from
the deck, sets it aside, then draws a second card. Roman wins if the color of the first card is the same color of
the second card. If the first card that Roman daws is red, what is the probability that he will win on his next
draw?

see explanation

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -

the eight graders whould be the answer
