Question

Three coins are tossed simultaneously, find the
probability of getting at least 2 heads.
ans=1/2 if you know then solve!!​

Answer 1

Answer:

possible outcomes = (HHH, HHT, HTH, THH, HTT, THT, TTT)

let A be the event of getting at least 2 heads

thus, possible outcomes = (HHH, HHT, HTH ,THH) = 4

P (at least 2 heads) = 4/8 = 1/2
