Abag contains six red and ten black marbles if you pick a marble from the bag what is the probability that the marble will be black. if you pick a marble record it’s color and return it to the back 200 times how many times can you expect to pick a black marble

125

Step-by-step explanation:

The total number of marbles is 6+10 = 16

P (black) = black / total

               = 10/16  = 5/8

With 200 draws, take the probability of P(black) times 200 since the marble is returned each time

200 * (5/8) = 125

We would expect to get 125 black marbles
