Question

find the probability of getting at least one tails when two coins are tossed​

Answer 1

Answer:

probability=favourable outcome/total outcome

=3/4

Answer 2

Answer:

1/4. explanation: p(E)of getting a tail = no of occurrence/ total no of coins are tossed. probability of occurrence=(H,H) ,(H,T),(T,H),(T,T). no of occurring at least one tail = (T,T). therefore, total no of occurrence/total no of coins are tossed =1/4
