Question

A mobile game uses two servers to handle matchmaking: one on the West Coast and one on the East Coast. The East server has 50 free users and 20 premium users, while the West server has 40 free users and 40 premium
users. While the process for selecting the next user is random, there is a preference given for premium users: on each pick there is a 60% than a premium user is selected and a 40% chance a free user is selected.
What is the probability that the next player will be a free user from the East server?

Answer 6

from east coast.
40% of 50 = 20 free users..
and 60% of 20 is 12 random user..
from west coast..
40% of 40 is 16 free user
and 60% of 40 is 24 random users
total users = 20+24+16+12=72 free users from east coast.=20
so its probablity is 72/20
36/10=3.6 ...
