Question

Discrete Random Variables
Procedure: The experiment is to pick one card from a deck of shuffled cards.
1. What is the theoretical probability of picking a diamond from a deck? ___________
2. Shuffle a deck of cards.
3. Pick one card from a deck of shuffled cards.
4. Record whether it was a diamond or not a diamond.
5. Put the card back and reshuffle.
6. Do this a total of 10 times.
7. Record the number of diamonds picked.
8. Let X = number of diamonds. Theoretically, X ~B( ____,____)
OK so we received data: from 22 students, and how many times they pulled a diamond from a deck

Answer 1

ybarrap so, one of my primary questions, that i am confused about ... is when I put in the data into the frequency table am I dividing the data by the amount of people that performed the experiment, or (10) the amount of times the experiment was performed.

Answer 2

The professor gave some examples and she made it seem as if this data is from 10 rather than 22

Answer 3

It's just two-category frequency distribution.

Something like this

Answer 4

ok but i mean this one...

Answer 5

ybarra, the suspense is killing me

Answer 6

There were 22 students, right? And each picked 10 cards?

Answer 7

yes, but in the data we received some put 1, 2, 3 4, 5, for the amount of diamonds they got out of ten cards

Answer 8

The only way this would make sense is if there are 10 students and each line represents the number of cards that were diamonds. The relative frequency would be the this number divided by the total cards that they picked.

Answer 9

no, we got 22.... so I put it in like this...
