Answer to Question 1

A.Using a pin number with a debit card.

FEEDBACK:
The video says that using a credit card is a safer option than using a debit card because the credit card typically offers additional safeguards for fraud. The video also says to vary passwords to online accounts, change those passwords frequently, and to sign when using a debit card instead of using a pin. Thus, the choice that the video did not recommend is using a debit card with a pin.

2.The video states that 78 of people carry less than 50 in cash; 40 carry less than 20 in cash, and 9 carry no cash. This suggests that if you randomly choose a person and ask them how much cash they are carrying, the probability that they are carrying more than 50 is:

A. 1.00
B. 0.78
C. 0.22
D. 0.09

C. 0.22

FEEDBACK:
If 78 of people carry less than 50 in cash, this means that the probability that a randomly selected person carries less than 50 in cash is 0.78 . This also means that the probability that a randomly selected person carries more than 50 in cash is 1- 0.78 = 0.22

Answer to Question 2

B.5

FEEDBACK:
If they perform 10 independent trials and the probability of success in one trial is 0.5, then you would expect that they would be successful half the time. That is, you expect they would find a car under their chosen cup 5 times.
