Abag contains 6 white beads and 4 black beads. you pick out a bead, record its color, and put the bead back in the bag. you repeat this process 35 times. which is the best prediction of how many times you would expect to remove a white bead from the bag?

6+4 = 10, so there is a total of 10 beads in the bag.

6/10 or 60% of the beads are white.

4/10 or 40% of the beads are black.

The question asks how many times you would expect to remove a white bead from the bag, so you just multiply the probability of removing a white bead times the number of times you picked beads out of the bag.

0.6 * 35 = 21

Therefore, the best prediction of how many times you would expect to remove a white bead from the bag is 21 times.

1.17+3.99a. you combine the terms with a to create 3.99 and the 1.17 stays because it has no like terms or a variable
