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=​"an even number less than 7​."

Answer 1

The probability of each outcome is $\frac{1}{10}=0.1.$

There are three even numbers less than 7.

P(X=an even number less than 7)$=3*0.1=0.3.$
