Question

An unbiased coin is tossed. What is the
probability of getting
(a) a head and (b) a tail?
​

Answer 1

Answer:

a head is probability of getting

Answer 2

Answer:

Let the total number of outcomes be s

s = {H,T}

n(s) = 2

(a) Let A be the probability of getting a head

n(A) = 1

P(A) = n(A)/ n(s)

= 1/2

(b) Let B be the probability of getting a tail

n(B) = 1

P(B) = n(B)/ n(s)

= 1/2
