Problem 1. Consider a survey on the number of hours of workout per week and the place of birth (response options City (C), Suburb (S), Small town (T), Rural (R)) for students of this class.
Create a cross tabulation.
Use it to find a frequency distribution table for the place of birth.
Are people born in a city more likely to workout than those born in the suburbs?

Problem 1. Find the following probabilities (assuming equally likely outcomes).
Of two heads in two coin tosses.
Of rolling an even number on a dice
Of event A: rolling two even numbers on two dice; and of event B: of rolling a sum of 7 on two dice.
Of event A: drawing a face card (K,Q,J) from a deck of cards; and of event B: drawing a heart from a deck of cards.
Of event A: drawing two face cards; and of event B: drawing two hearts from a deck of cards.
(Relative frequency method for assigning probabilities)
Problem 2. A dice is suspected to not be fair. It is rolled 1000 times and the following relative frequencies are noted:
What is the relative frequency of 6?
Taking the relative frequency to be the probability of the respective dice rolls, comment on whether its a fair dice
What is the probability of event A: rolling 3 or 4?
What is the probability of event B: rolling an even number?
I want to simulate a fair coin toss with this dice, how will you do it?
