Answer:

35. a, 36. c, 37. b 38.

Step-by-step explanation:

35. If you connect all the points in clockwise order, a shape should appear. Since all possible lines include the shape's perimeter + diagonals. If there are n points on the board, the total of the lines would be n×(n-3)/2+n=. If you put 10 the answer would be 45.

36. The carousel is circle-shaped. So if there are n wooden horses, the ways would be 10×9×8×7...×2×1 /10. We divide the numbers 10 because it is a circle.

37. Same method as 35.

38. There is a total of five possibilities of picking up the marble. 4 Reds and 0 Blues, 3 Reds and 1 Blue, 2 Reds and 2 Blues, 1 Reds and 3 Blues, and 4 Blues.

Since we have the question of least it has to be 4 Reds and 0 Blues, 3 Reds and 1 Blue, 2 Reds and 2 Blues,

Sorry about not answering the rest of the questions. I am in a bit of a hurry

Back to the cards! In poker, a flush is when all five cards are the same suit. Find the probability of being dealt a flush (when

12345 [234]

<span> a) 13 we know that the number of clubs in the deck/52 that the total number of cards in the deck =0 .25= 25%.
b) 12 the remaining number of clubs in the deck/51 the remaining number of cards in the deck = 0.235= 23.5%.
c) 11 same as above/50 the same as above = 0.22= 22%
d) 10/49 = 20.4%
e) 9/48 = 18.75%
f) The combinations that can be made with certain characteristics are limited to say: ace of clubs to 12 other clubs, two of clubs to 12 other clubs, three of clubs to 12 other clubs, etc. As the desired outcome is reached, the probable outcome percentages must be multiplied together to accommodate all combinations. the probability is .049%.
g) probability of dealt a flush is 13*12*11*10*9*4/52*51*50*49*48 = 617,760/311,875,200 = 0.00198079232, or 0.2% when round up. This is any of the 13 cards needed in a particular suit, times any of the remaining 12, times any of the remaining 11 after that, and so on multiplied by 4 since there are four suits in which this can occur. This is divided by the number of cards in the deck 52 times the remaining cards when that's drawn, and so on and so forth. </span>
