Given the statement:
Martha believes that the probability of her being selected for the lead role in the play is 4/11.
Determine the probability of her not being selected.
Solution:
In order to determine the probability of her not being selected, we simply subtract the probability of her being selected to 1. Since we have a fraction 4/11, we can equate 1 as a fraction in order to easily subtract. In this case, 1 can be written as 11/11.
= 1 - 4/11
= 11/11 - 4/11
= 7/11
Final answer:
C. 7/11
