Given are 9 cards out of which 3 are Hearts, 3 are Clubs, 3 are Diamonds.
It says to draw 2 cards out of 9 cards, so Sample selection would be 9C2.
Favourable outcome is 2 heart cards, so Favourable selection would be 3C2.
Now the probability would be Favourable selection over Sample selection.
probability =  \frac{3c2}{9c2 }  =  \frac{ \frac{3 \times 2}{2 \times 1} }{ \frac{9 \times 8}{2 \times 1} }  =  \frac{3 \times 2}{9 \times 8}  =  \frac{1}{12}

Hence, option D i.e. 1/12 is the final answer.

Doss [256]

Answer:

The answer to your question is (7, 0)

Step-by-step explanation:

Data

A (7, 3)

B (0, 7)

C (7, 0)

D (3, 7)

Process

Point A           y - 3 = m(x - 7)

Point B           y - 7 = m(x - 0)

Point C           y - 0 = m(x - 7)

Point D           y - 7 = m(x - 3)

2.- Conclusion

The only possibility is that m = 3 and the answer will be the third point (7,0)
