A ba contains 5 white, 7 red and 8 black balls. If five balls are drawn one by
one with replacement. What is the probability that all are white?

Respuesta :

Answer:

1/1024

Step-by-step explanation:

First you find the number of white balls out of the number of total balls:

5/20

Now every time the chance of getting a whit ball is 5/20, so now you times it all:

5/20*5/20*5/20*5/20*5/20

Now you have your answer:

3125/3200000=1/1024
