## gabbyalicorn one year ago Hitomi has a bag with four chips in it numbered 1 to 4. She randomly draws a chip and replaces it three times. What is the probability that Hitomi will draw a 1 all three times?

HI! (again)

2. gabbyalicorn

Hello!

3. misty1212

what is the probability she draws a one on the first try?

4. gabbyalicorn

3/4 or 1/4 ?

5. misty1212

hmmm pick one (hint, there is only one "one")

6. gabbyalicorn

i think 1/4

7. misty1212

right!

8. gabbyalicorn

:D

9. misty1212

and since she replaces it, the probability she gets it on the second try is also $$\frac{1}{4}$$

10. misty1212

and also on the third try!

11. gabbyalicorn

so add 1/4 + 1/4 + 1/4?

12. misty1212

so all three, do $\frac{1}{4}\times \frac{1}{4}\times \frac{1}{4}$

13. misty1212

14. gabbyalicorn

oh, multiply. Sorry.

15. misty1212

you want to multiply them together

16. gabbyalicorn

1/64

17. misty1212

it is an AND statement one and one and one

18. misty1212

right

19. gabbyalicorn

:D
