A dice was thrown 80 times and the frequency of occurrence of 2, 3, 5 and 6 is given in the table. What is the probability of occurrence of 1 or 4?
0.25
0
Total frequency of occurrence of 2, 3, 5 and 6 = 60.
Frequency of occurrence of 1 or 4 = 80 - 60 = 20.
Probability of occurrence of 1 or 4 = Frequency of occurrence of 1 or 4Total number of times die is thrown
So, probability of occurrence of 1 or 4 = 2080 = 14 = 0.25
