1.0/ 1.0 PointsQuestion 20 of 20A box is filled with several party favors. It contains 12 hats, 15 noisemakers, 10 fingertraps, and 5 bags of confetti. Let H = the event of getting a hat. Let N = the event of getting anoisemaker. Let F = the event of getting a finger trap. Let C = the event of getting a bag of confetti. FindP(C). Feedback: P(M or No) = P(M) + P(No) - P(M and No) (50/100) + (20/100) - (10/100) Feedback: 5/42 Powered by Sakai Copyright 2003-2020 The Apereo Foundation. All rights reserved.
