Answer: = 0.2465

Step-by-step explanation:

Firstly the probability that a random requisition is entered by data entry specialist 1 equals 0.3, by data

entry specialist 2 equals 0.45, by data entry specialist 3 equals 0.25.

probability (p1) =

(0.3 * 0.03

) / (0.3 * 0.03 + 0.45 * 0.05 + 0.25 * 0.02) = 0.2465
