➷ 5 + 3 + 3 + 4 = 15

5/15 * 5/15 = 25/225

This can be simplified to 1/9

Total cards = 4 + 5 + 3 + 3 = 15 cards.

There are 5 queens, picking 1 queen would equal 5/15 which reduces to 1/3.

Because the queen is replaced and then you pick again, the probability would be the same as the first time. 1/3.

To find the overall probability of picking 2 queens, multiply each probability together: 1/3 x 1/3 = 1/9 total probability.

murzikaleks [220]

Answer:

1615

Step-by-step explanation:

Area of triangle is: A= B•H•1/2

Area of square is A= L•W

39•17•1/2= 331.5

331.5•4= 1326

17•17= 289

Add the square area to the area of the triangles

289+ 1326= 1615
