You have a bag with 6 marbles. one marble is white. you reach the bag 100 times. after taking out a marble, it is placed back in the bag. what is the probability of drawing a white marble at least once?

0.999999988

Step-by-step explanation:

Given that you  have a bag with 6 marbles. One marble is white. You reach the bag 100 times. After taking out a marble, it is placed back in the bag.

Because every time you replace the marble drawn, the probability for drawing a white marble in one draw is constant = p =5/6

No of trials n = 100

Here X no of times white marble is drawn is Binomial since there are two outcomes and also the probability is constant.

the probability of drawing a white marble at least once

=

Required probability is almost 1.
