A pound has 60 German Shepherds and 40 Great Danes of both sexes. If they breed with each other randomly, what is the probability that the puppies are: (i) pure breed German Shepherds, (ii) pure breed Great Danes, (iii) German Shepherd-Great Danes

(i) pure breed German Shepherds,= 0.6

(ii) pure breed Great Danes,= 0.4

(iii) German Shepherd-Great Danes= 0.24

Step-by-step explanation:

The probability of success for the German shepherd is 60/100 0r 6/10 0r 0.6

The probability of failure for the German shepherd is 40/100 0r 4/10 0r 0.4

The probability of success for the Great Danes is 40/100 0r 4/10 0r 0.4

The probability of failure for the Great Danes is  60/100 0r 6/10 0r 0.6

The probability that it is a pure German shepherd is 60/100 0r 6/10 0r 0.6

The probability that it is a pure the Great Danes is 40/100 0r 4/10 0r 0.4

The probability that the puppies are: German Shepherd-Great Danes is given by  since the events are independent

P (GS ∩ GD) = 0.6* 0.4= 0.24

gdp is the best phrase!

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".
