Question

Let the sample space be S = {1,2,3,4,5, 6, 7, 8, 9, 10). Suppose the outcomes are equally likely. Compute the probability of the event E = {4, 5, 6, 7).P(E)=(Type an integer or a decimal. Do not round.)

Answer 1

The probability of the event E is the number of elements in the event divided by the number of elements in the sample space.

S has 10 elements, E has 4 elements:

`P(E)=(4)/(10)=(2)/(5)`

The probability of the event E is 2/5.
