Of the 250 students, 100 plan to major in mathematics, 80 plan to major in computer science, and 20 plan to pursue a double major in mathematics and computer science. Using this information, answer each of the following questions.
Let M be the event that a randomly selected student plans to major in mathematics and C be the event that a randomly selected student plans to major in computer science.
1) What is P(M) the probability that a student plans to major in mathematics?
2) What is P(C) the probability that a student plans to major in computer science?
3) What is P(M and C) the probability that a student has decided to major in mathematics and computer science?
4) What is P(M or C) the probability that a student has chosen to major in mathematics or computer science?
