Math Problem Statement

classify each pair of events as mutually exclusive or - non-mutually exclusive. a.) event a: randomly drawing a grey sock from a drawer, event b: randomly drawing a wool sock from a drawer. b.) event a: randomly selecting a student with brown eyes, event b: randomly selecting a student on the honour roll. c.) event a: having an even number of students in your class, event b: having an odd number of students in your class. d.) event a: rolling a six with a die, event b: rolling a prime number with a die. e.) event a: your birthday faolling on a saturday next year, event b: your birthday falling on a weekend next year. f.) event a: getting an A on the next test, event b: passing the next test. g.) event a: calm weather at noon tomorrow, event b: stormy weather at noon tomorrow. h.) event a: sunny weather next week, event b: rainy weather next week.

Solution

Here is a classification of each pair of events as either mutually exclusive or non-mutually exclusive:

a.) Event A: Randomly drawing a grey sock from a drawer.
Event B: Randomly drawing a wool sock from a drawer.

  • Classification: Non-mutually exclusive (A grey sock could also be a wool sock.)

b.) Event A: Randomly selecting a student with brown eyes.
Event B: Randomly selecting a student on the honour roll.

  • Classification: Non-mutually exclusive (A student could have brown eyes and also be on the honour roll.)

c.) Event A: Having an even number of students in your class.
Event B: Having an odd number of students in your class.

  • Classification: Mutually exclusive (The number of students in the class can either be even or odd, but not both.)

d.) Event A: Rolling a six with a die.
Event B: Rolling a prime number with a die.

  • Classification: Non-mutually exclusive (The number 6 is not prime, but you can roll either a 2, 3, or 5, which are prime numbers.)

e.) Event A: Your birthday falling on a Saturday next year.
Event B: Your birthday falling on a weekend next year.

  • Classification: Non-mutually exclusive (If your birthday falls on a Saturday, it's also part of the weekend.)

f.) Event A: Getting an A on the next test.
Event B: Passing the next test.

  • Classification: Non-mutually exclusive (If you get an A, you also pass the test.)

g.) Event A: Calm weather at noon tomorrow.
Event B: Stormy weather at noon tomorrow.

  • Classification: Mutually exclusive (The weather cannot be both calm and stormy at the same time.)

h.) Event A: Sunny weather next week.
Event B: Rainy weather next week.

  • Classification: Non-mutually exclusive (It's possible for there to be sunny weather on some days and rainy weather on others during the week.)
