Answer:
(B) 0.0588
Step-by-step explanation:
The probability is calculated as a division between the number of possibilities that satisfy a condition and the number of total possibilities. Then, the probability that the first card is diamonds is:

Because the deck has 52 cards and 13 of them are diamonds.
Then, if the first card was diamonds, the probability that the second card is also diamond is:

Because now, we just have 51 cards and 12 of them are diamonds.
Therefore, the probability that both cards are diamonds is calculated as a multiplication between
and
. This is:

Answer:
-6=7 NO SOLUTION
Step-by-step explanation:
First, distribute the -3 to the (k +2)
Your equation becomes, -3k-6=-3k+7
Add 3k to both sides to have the variables be on the same side
Your equation becomes, -6=7
Since that isn’t true, it’s a no solution
