First let us determine the total number of combinations that can be made from these pair. The number of combinations can simply be calculated by multiplication, so:

Combination = 4 * 4 = 16

Since we know that for each shirt color, there is a corresponding sock with the same color. So there are 4 matching pairs. Therefore the unmatching pairs are 12. Calculating the probability to get unmatching pair would be:

Probability of unmatching pair = 12/16 = 0.75

Interpretation: There is a 75% probability that his socks and shirt wont match.

For what values of x and y must ABCD be a parallelogram?
n200080 [17]
<h2>x^{\circ}=21^{\circ} \ and \ y^{\circ}=39^{\circ}</h2>

Step-by-step explanation:

We know that vertically opposite angles of a parallelogram are equal .

\angle ABC =\angle ADC\ and \ \angle BAD = \angle DAC

⇒3x^{\circ}=(4x-21)^{\circ} \ and \ 3y^{\circ}=(y+78)^{\circ}

⇒3x^{\circ}-4x^{\circ}=-21^{\circ} \ and \ 3y^{\circ}-y^{\circ}=78^{\circ}

⇒-x^{\circ}=-21^{\circ} \ and \ 2y^{\circ}=78^{\circ}

⇒x^{\circ}=21^{\circ} \ and \ y^{\circ}=39^{\circ}
