Explain Click to selecr your answer(s 2-11 PM ^! Eel 11/24/2017 Typehere to searchExplanation / Answer
a) Probability that the person chosen is opposed to the change or is a female
= ( Total people opposed to change + Total females - Total females opposed to change ) / Total number of people
= ( 619 + 563 - 294 ) / 1060
= 0.838
Therefore 0.838 is the required probability here.
b) Probability that the person supports the change or is a male
= ( Total people who supports to change + Total males - Total males who supports the change ) / Total number of people
= ( 409 + 497 - 164 ) / 1060
= 0.7
Therefore 0.700 is the required probability here.
c) Probability that a person is not unsure or is a female
= 1 - Probability that a person is male and unsure
= 1 - (8/1060)
= 0.992
Therefore 0.992 is the required probability here.
d) The events being male and support are not mutually exclusive events because we can clearly see that there are some males who are in support.
