The probability of a hand of 13 cards contains all 4 of one of the denominations, say Aces, is given by:

The same probability applies to getting all 4 of each of the other denominations.
Therefore the required probability is:

The answer is 0.0343.
<u><em>Answer:</em></u>
The length of the diagonal is 284 km
<u><em>Explanation:</em></u>
<u>1- we get the side length of the side:</u>
We are given that the land has a square shape and an area of 40,404 km²
Area of square = (side)²
40,404 = (side)²
side = +√40,404
side = 201.007 km ≈ 201 km
<u>2- we get the length of the diagonal:</u>
Refer to the attach picture representing the area of land.
We can infer that the two side lengths along with the diagonal of the land form a right-angled triangle.
Therefore, to get the diagonal, we can apply the Pythagorean theorem as follows:

Diagonal = 284.2 ≈ 284 km

Answer:
(a) 15
Step-by-step explanation:
Each of the marked angles is an exterior angle of the polygon. The sum of exterior angles is always 360°. We can use that fact to write the equation.
4x° +77° +59° +6x° +74° = 360° . . . . . an equation to find x
10x + 210 = 360 . . . . . . . . . . . . . . divide by °, collect terms
x + 21 = 36 . . . . . . . . . . . . . . . divide by 10
x = 15 . . . . . . . . . . . . . . . subtract 21

<em>Comment on the sum of exterior angles</em>
Imagine the figure shrunk smaller and smaller until all of the angle vertices are the same point. You can see that those angles will completely fill the angular space around that central point, so they must have a sum of 360°.
