Question

Of the 44 players attributed to a playwright 11 are comedies 17 are tragedies and 16 are histories if one play is selected at random find the odds against selecting a tragedy

Answer 1

Explanation:

since the total number of players is 44, the Universal set will also be 44.

let C be the set for Comedy

let T be the set for Tragedy

let H be the set for Histories

ξ = { 44 }

C = { 11 }

T = { 17 }

H = { 16 }

probability T = (17/44)

odds of selecting T = probability not T

= 1 - probability T

= 1 - ( 17/44)

= 27/44

you need to give the answer as a ratio of odds of selecting T against chances of selecting T;

if out of 44 players, the chances of not selecting T is 27 and the chances of selecting T is 17, then:

odds against selecting random is, 27: 17

that's the answer. hope this helps you!
