Question

If S( 1, 2, 3, 4, 5,6 ) find the probability that a number chosen is more than 4

Answer 1

1/3

Explanation:

The list of sample space's elements: {1, 2, 3, 4, 5, 6}

The number of elements in sample space: 6

The list of elements belonged to the event "choosing the number larger than 4": {5, 6}

The number of elements in the event: 2

Hence, the probability of event "choosing a number larger than 4":

P = number of event's elements/number of sample space's elements

= 2/6

= 1/3

Answer 2

`|\Omega|=6\\|A|=2\\\\P(A)=(2)/(6)=(1)/(3)`
