Question

A coin is tossed 3 times. List the possible outcomes. Find the probability of getting (1) all heads (2) at least 2 heads (3) at least one heads

Answer 1

sample space of the coin.
(2) cube =8 sample space
H, H, H
H, H, T
H, T, H
H, T, T
T, H, H
T, H, T
T, T, H
T, T, T
1. n(e) =all heads =1(H, H, H)
N(S) = 8
p(e) = 1 upon 8

2. n(e) = atleast two heads = 4 (H,H,T) (H,H,H) (H, T, H) (T, H, H,)
N(S) =8
P(E) = 2upon 8 = 1 upon 4

3. n(e) = atleast one head =7(H, H, H) (H, H, T) (H, T, H) (H, T, T) (T, H, H) (T, H, T) (T, T, H)
N(S) =8
P(E) =7 upon 8
