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={2, 4}.

Answer 1

0.2

Explanation:

we have given sample space = {1,2,3,4,5,6,7,8,9,10}

favorable outcomes E={2,4}

we know that probability is defined as the ratio of favorable otcomes to the sample space

probability
`P=(favorable\ outcomes)/( sample\ space )`

we have favorable outcomes E={2,4} that is favorable outcomes=2

and sample sapce = {1,2,3,4,5,6,7,8,9,10}

so the probability
`p=(2)/(10)=0.2`
