29 + 29 + 13 = 71
The range of possible times in seconds for x is 28:30 - 29:29. Similarly for y.
The range of possible times for z is 12:30 - 13:29
The range of possible values for x + y + z = 69:30 - 72:27 which is 178 seconds long
To be recorded as 72 minutes the sum would be in the range 71:30 - 72:27 which is 58 seconds long
P(result recorded as 72 min) = 58/178
If you simply used the ranges [28.5, 29.5) [28.5, 29.5) and [12.5, 13.5)
then the sum would be in the range [69.5, 72.5)
and P(result recorded as 72 min) = 60 seconds / 180 seconds = 1/3
Using discrete times in seconds gives a slightly different answer but is also much harder to understand.
Answer: X or SR = 3.6
Step-by-step explanation: Simply divide TP and EA or one of each similar segments to get a number. Which 4.8 / 4 = 1.2 Then multiply this number by 3 to get your answer of x which is 3.6
