Question

Find the probability of choosing a red marble from a bag of 9 white marbles and 1 red marble, with replacement of each drawn marble.

Answer 1

1/10

Answer 2

there is one red marble out of 10 marbles,

Answer 3

But it says with replacement, so it would be the same?

Answer 4

yes because a marble is picked out only once not multiple times.

Answer 5

Ah okay I understand it now. Thanks!

Answer 6

if it was picked out 2 times, and the question was "whats the probability of a red being picked both times, with replacement," the answer would be 1/100. just 1/10 times 1/10.
