defon

Answer:

5/13 for Todd running next day if this helps?

I counted the days and then counted 13 was the total so it is 5/13

Step-by-step explanation:

Days = 2,+3,+3,+ 5 = 13

13= 5/13 = probability

13 = 8:5 = ratio

5/13 was the probability of the results reoccurring same as day 5

Just as results being under 3km would only be 2/13
