Loretta is rolling an unfair 6 sided die with a single number between 1 and 6 on each face. she has a 70% chance of rolling a four. she is playing a game with a friend and knows that if she rolls a four on three of her next five rolls she will lose the game. she wants to determine the probability that she rolls a four on three of her next five rolls.
which simulation design has an appropriate device and a correct trial?
a) using a fair coin let heads represent rolling a four and tails represent not rolling a four. flip the coin five times.
b) using a table of random digits select a digit between 0 and 9. let 0-6 represent rolling a four and 7-9 represent not rolling a four. select five digits.
c) roll a fair die with a single digit between 1 and 6 on each face. let four represent rolling a four and 1-3 and 5 and 6 represent not rolling a four. roll the die five times.
d) using a table of random digits select a digit between 1 and 6, ignoring digits 0, 7, 8, and 9. let 4 represent rolling a four and 1-3 and 5 and 6 represent not rolling a four select five digits.
