Step 1
Once you draw a ball from the first urn and put it into the second urn, the second urn will contain 6 balls, with 4 being red (the first urn does not contain any red balls).
Since you have an equal probability of drawing any ball from the second urn, the probability of drawing a red ball is
46=23 or 6623%
