Question

Fill in the blanks please

Answer 1

For a given distribution of data, the sum of the relative frequencies is 1.

Thus, the completed table of relative frequencies is gives as:

Outcome      1      2      3      4      5
Rel. Freq.   0.1   0.1   0.3   0.1   0.4


Part a:

P({2, 3, 4}) = 0.1 + 0.3 + 0.1 = 0.5


Part b: 

P(E') where E = {3, 4}

= 1 - P({3, 4}) = 1 - (0.3 + 0.1) = 1 - 0.4 = 0.6
