Answer:
A coin is weighted so that the head is twice as likely to appear as the tail. When such ... =>p+2p=1 =>p=1/3 i.e. probability of getting tail in a single toss=1/3 ... The sample space is S = { H, H, T}. So, n(S) = ... How would you find the probability of getting exactly two heads
Explanation:
I only know it's a process of change of matter but I don't remember the exact types
