5* = 1/1 * 1/2 * 1/3 * 1/4 * 1/5 = 1 / (2*3*4*5)
4* = 1/1 * 1/2 * 1/3 * 1/4 = 1 / (2*3*4)

5*/4* = (2*3*4)/(2*3*4*5) = 1/5

E if inclusive.

But if t is between k an 1 (not inclusive.. as was originally written) the answer is 1/4

Exactly. I was looking for the word inclusive. Q never said that. So 5* would be 1/2 * 1/3 * 1/4

Its D.

5* = 1/2* 1/3 *1/4 (between 1 and k , k =5 )

4* = 1/2 * 1/3 (between 1 and k , k =4 )

so 5* / 4* = 1/4

Thanks
