Answer 2

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

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
