1. The missing question here is : "what is the probability that the mail sorter placed each letter correctly"?
2. Name the letters L1, L2, ....L8 (Letter 1, Letter 2.... Letter 8)
3. The first letter has a probability of 1/25 to be placed in the correct mailbox.
Each of the remaining 7 letters have 1/25 probability, and these probabilities are related.
4. So the probability that each letter goes to the proper mailbox is
Step-by-step explanation:
The outlier is excluded, so the minimum is 59.

Answer:
t=40
Step-by-step explanation:
The sum of all angles in a triangle will always equal 180°. This means that:
(2t-42)+(4t-49)+(2t-49) = 180°
Let's solve this equation!
(2t-42)+(4t-49)+(2t-49) = 180
First we simplify what's on the left side:
2t-42+4t-49+2t-49 = 180
2t+4t+2t-42-49-49 = 180
8t-140 = 180
*Add 140 to both sides
8t = 180+140
8t = 320
Divide both sides by 8 to know what t means:
t = 320/8
t = 40
