(1) Getting at least one head.
Solution:
Given two coins are tossed
Sample Space, S = (HH, HT, TH, TT)
Probability of getting at least one head, p(A) =
p(A) = ¾
(2) Getting no head.
Solution:
Given two coins are tossed
Sample Space, S = (HH, HT, TH, TT)
Probability of getting no head, p(B) =
p(B) = ¼
