Question

HELP PLEASE!!! Math question

Answer 1

(a).
`(3)/(7)`

(b).
`(4)/(13)`

Explanation:

(a). Odds in favor of winning a new T.V. =
`(4)/(7)`

Or probability of not winning a new T.V. =
`(4)/(7)`

Since, Probability to win a T.V. + Probability of not winning the new T.V. = 1

Probability of winning a new T.V. = 1 - Probability of not winning a new T.V.

= 1 -
`(4)/(7)`

=
`(7-4)/(7)`

=
`(3)/(7)`

(b). Probability of winning the match + probability of not winning the match = 1

`(9)/(13)` + Probability of not winning the match = 1

Probability of not winning the match = 1 -
`(9)/(13)`

=
`(13-9)/(13)`

=
`(4)/(13)`
