I have 100 users in a feeder file. Out of 100 users 15% of users should add 20 items into the basket and 25% of users should add 40 items into the basket and 30% of users should add 50 items into the basket and 20% of users should add 60 items into the basket and 10% of users should add 70 items into the basket. Currently, I have a script which adds 50 items in the basket how to modify that script to achieve the above requirement.
