BACKBURNER Introduction to probability

Google Classroom
Assuming each outcome is equally likely, the probability of a given event is successful outcomes/possible outcomes.
(Teach a bit about probability here. Maybe include a short vid.)
The faces of a fair 6-sided die are numbered from 1 to 6. What is the probability that when it is rolled, a 2 is facing up?
P(2 facing up)=
  • Your answer should be
  • an integer, like 6
  • an exact decimal, like 0.75
  • a simplified proper fraction, like 3/5
  • a simplified improper fraction, like 7/4
  • a mixed number, like 1 3/4
What is the probability that when a fair 6-sided die is rolled, a prime number faces up?
P(prime)=
  • Your answer should be

A standard deck of cards has 52 cards divided into 4 suits, each of which has 13 cards. Two of the suits are red, the other two are black. The cards in the deck are placed in random order.
In how many ways can we pick a card?
  • Your answer should be
  • an integer, like 6
  • an exact decimal, like 0.75
  • a simplified proper fraction, like 3/5
  • a simplified improper fraction, like 7/4
  • a mixed number, like 1 3/4
Then, in how many ways can we pick a second card?
  • Your answer should be
  • an integer, like 6
  • an exact decimal, like 0.75
  • a simplified proper fraction, like 3/5
  • a simplified improper fraction, like 7/4
  • a mixed number, like 1 3/4
In how many ways can we pick a red card?
  • Your answer should be
  • an integer, like 6
  • an exact decimal, like 0.75
  • a simplified proper fraction, like 3/5
  • a simplified improper fraction, like 7/4
  • a mixed number, like 1 3/4
Then, in how many ways can we pick a second red card?
  • Your answer should be
  • an integer, like 6
  • an exact decimal, like 0.75
  • a simplified proper fraction, like 3/5
  • a simplified improper fraction, like 7/4
  • a mixed number, like 1 3/4
What is the probability that the first two cards are both red?
  • Your answer should be
  • an integer, like 6
  • an exact decimal, like 0.75
  • a simplified proper fraction, like 3/5
  • a simplified improper fraction, like 7/4
