Answer:
The probability that a randomly selected survey participant didn't got the flew = 0.75
Step-by-step explanation:
Students got the flu during Winter 2013 = 12 %
Students got the flu during Winter 2014 = 18 %
Students got the flu during both years = 5 %
Students got the flu at least in one year = 12 + 18 - 5 = 25 %
Students didn't got the flew = 100 - 25 = 75 %
⇒ The probability that a randomly selected survey participant didn't got the flew =
⇒ 0.75
This is the probability that a randomly selected survey participant didn't got the flew.

b. No
Step-by-step explanation:
To find if an ordered pair is a solution to the inequality, substitute its x and y values for the x and y in the inequality and solve. If the equation is true, then it is a solution. If it is not, then it is not a solution.
1) First, substitute the x and y values of (3, 1) into the inequality. So, substitute 3 for x and 1 for y:
1 is greater than or equal to 1, so (3,1) is a solution.
2) Second, do the same with the point (1, -4). Substitute 1 for x and -4 for y:
However, -4 is not greater than or equal to -3, thus (1, -4) is not a solution.
