a bank gives away 1 out of 5 cards evry time a client deposits. there is an equal chance of getting one of the cards. predict the number of times a client will have to make a deposit to get all five cars. which can NOT be considered a trial for the simulation.

1) use digits 1-5 each number represents a basketball card. use random number generator on graphing calculator.

2) divide a spinner into five equal parts. labeled A to E. spin spinner to land on all five letters.

3) place 5 balls of diff. colors of box. draw one ball record color and replace ball in box. repeat until all five colors are picked.

4) use number cube toss and record number which it lands. repeat utill you get all numbers

i think the answer is 4

To solve this problem, we need to consider each scenario individually and determine which option is the correct one.

1) Using digits 1-5: In this scenario, we would use a random number generator to generate a number between 1 and 5. We would repeat this process until we have all five numbers. This approach might work, but we have no way of knowing how many tries it would take to get all five numbers. So, this option cannot be considered a trial for the simulation.

2) Using a spinner: In this scenario, we would divide a spinner into five equal parts labeled A to E. We would spin the spinner repeatedly until we land on all five letters. Similar to the first option, we have no way of knowing how many spins it would take to hit all five letters. Thus, this option also cannot be considered a trial.

3) Using balls of different colors: In this scenario, we would place 5 balls of different colors into a box. We would draw one ball, record its color, and then replace the ball in the box. We would repeat this process until we have picked all five colors. This option seems to be suitable for our simulation, as we can calculate the expected number of draws required before drawing all five colors.

4) Using a number cube: In this scenario, we would toss a number cube and record the number it lands on. We would repeat this process until we have all five numbers. Similar to the previous options, there is no way to determine how many tosses it would take to get all five numbers. Consequently, this option also cannot be considered a trial for the simulation.

Therefore, option 3, which involves drawing balls of different colors, can be considered a trial for the simulation. However, we need to calculate the expected number of draws required to completely draw all five colors, which would give us the prediction we are seeking.
