A coin is tossed 10 times and the outcomes are observed as
H, T, H, T, T, H, H, T, H, H
(H is Head; T is Tail)
What is the probability of getting Head?
D.
Given, outcomes are
H, T, H, T, T, H, H, T, H, H
Number of favorable outcomes, n(E)= 6
Total number of possible outcomes, n(S) = 10
Therefore, Required probability=
