#10-1 : what is the probability of randomly choosing a diamond card from a regular deck of 52 cards? what is the probability of choosing a club?

There are of each suit in a deck of cards.

This means the probability of drawing a diamond card is . You can divide the numerator and denominator each by to simplify.

Since there are the same number of clubs as there are diamonds, the probabilities are the same.

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
