If 30% of the people who shop at a local grocery store buy chocolate ice-cream, what is the probability that it will take at least 5 customers to find one who buys chocolate ice-cream?
which simulation design has an appropriate device and a correct trial for this problem?
a) roll a fair die where 1,2, and 3 are buying chocolate ice-cream and the other numbers are not buying chocolate-ice cream. roll the die until you get a 1,2,3. record the number of rolls it took you.
b) using a random digits table select one digit numbers where 0-2 is a customer who buys chocolate ice cream and 3-9 is a customer who does not. keep selecting one digit numbers until you get a 0-2. record the number of digits selected.
c) using a random digits table select one digit numbers where 0-3 is a customer who buys chocolate ice cream and 4-9 is a customer who does not. keep selecting one digit numbers until you get a 0-2. record the number of digits selected.
d) spin a spinner that is split up into 5 sections, where 1 section is a success of buying chocolate ice-cream and the other four sections are not buying chocolate ice-cream. keep spinning until you get someone that buys chocolate ice-cream. record the number of spins it took you
