Question

What is the theoretical probability that you will draw each of the following?

The green diamond card:





A number card:





A blue card:

Answer 1

1/12 green diamond

Answer 2

just count the possibilities
there is 1 green diamond card out of 12 cards

Answer 3

there are 4 number cards out of 12
4/12 simplifies to 1/3*

Answer 4

and there are 4 blue cards out of 12
so 4/12 simplifes to 1/3 again

Answer 5

can you help me with this too?


Does the probability that you will draw a shape or a purple star involve disjoint or overlapping events? What formula would you use to calculate this probability?

Answer 6

@dan815

Answer 7

what is the probability of drawing a shape

Answer 8

4/12?

Answer 9

and that will inclue the purple star shape too

Answer 10

think about it like this
what is the probability of drawing a shape that is not purple

Answer 11

3/12?

Answer 12

yep
and drawing a purple shape is 1/12
so 3/12 + 1/12 = 4/12

Answer 13

or would it be 3/11 since you wont get the purple star

Answer 14

okay

Answer 15

basically it is just an overlapping event so we only need to worry about the probability of drawing a shape thats it

Hi @yoyogators! I was wondering if you have this assignment still? If you do I was going to use it as an example for my sisters 7th grade assignment Thank You!
