1. Three unbiased coins are tossed. What is the probability of getting at most two heads?
Let E = event of getting at most two heads
Then, E = {TTT, TTH, THT, HTT, THH, HTH, HHT}
Solution:
Here S = [TTT, TTH, THT, HTT, THH, HTH, HHT, HHH]Let E = event of getting at most two heads
Then, E = {TTT, TTH, THT, HTT, THH, HTH, HHT}
