Sagot :

Answer:

4/8 or 1/2 or 0.5

Step-by-step explanation:

1. total possible events of sample space S

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

S=8

2. expected or successful events A

A = {HHH, HHT, HTH, THH}

A=4

3. Find the probability

P(A) = Successful Events/Total Events of Sample Space

P(A) = 4/8 or 1/2 or 0.5
