Yes!
it will be exactly at 1.41 if you round
Answer:

Step-by-step explanation:
-The total number of outcomes is 4.
-Given that the outcomes occur with the same frequency.
-Therefore they all occur with the same frequency, 1/4=0.25

-The probability distribution for the duration of a service call is attached.
x=(13±3√17)/2x
≈ 12.68465843, 0.31534156
Which would be 12.7 and 0.3 If you rounded to the nearest tenth.
.16 because the square root of 16 is 4, then you would want to divide 4 by 25.. which would equal .16 or 4/25
