Answer:

Probability of getting all heads = 1/8

Step-by-step explanation:

If a fair coin is tossed three times:

Let H represent head and T represent tail

The sample space is:

S = {HHH, HTT, HTH, HHT, THH, THT, TTH, TTT}

The number of the sample, n(S) = 8

The number of times we get all heads in the sample space, n(all heads) = 1

Probability of getting all heads, P(all heads) = n(all heads)/n(S)

P(all heads) = 1/8
