Given two jars of red and blue balls, find the probability of choosing a red ball from Jar 1 after going through the steps.
Step 1: Choose a random ball from Jar 2 and add it to Jar 1
Step 2: Choose a random ball from Jar 1
Step 3: Calculate the probability of the final ball being red
Given inputs for Jar 1 and Jar 2
Jar 1: (r1,b1) = (2,7)
Jar 2: (r2,b2) = (5,5)
Choose a ball from Jar 2 and add it to Jar 1.
_Note: Jar 1 could now have either 3 blue and 7 red or 2 blue and 8 red._
Taking into consideration both possibilities, the likelihood of the final ball being red is 0.25 .
