In a standard deck of cards there are 13 spades, 13 clubs, 13 hearts and 13 diamonds. the spades and the clubs are black. the hearts and the diamonds are red.
if two cards are chosen at random from a deck, one at a time, replaced after each pick, what is the probability that a black card is chosen first and a heart is chosen second?
options:
1/8
1/2
2/3
3/4

Sorry guys but as you have a small brain

Aline passes through 3,7 and 6,9 what equation represents the line

Asequence has its first term equal to 4, and each term of the sequence is obtained by adding 2 to the previous term. if f(n) represents the nth term of the sequence, which of the following recursive functions best defines this sequence? (1 point) f(1) = 2 and f(n) = f(n − 1) + 4; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2n; n > 1 f(1) = 2 and f(n) = f(n − 1) + 4n; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2; n > 1 i will award !
