A bag contains 33 red marbles, 6 white marbles, and 5 gray marbles. You randomly pick out a marble, record its color, and put it back in the bag. You repeat this process 220 times. How many white or gray marbles do you expect to get

Step-by-step explanation:

Total number of marbles = 33

Number of white marbles  = 6

Number of gray marbles  = 5

Now, as we need to pick white or gray marbles, so favorable outcomes

=  6+ 5  = 11 marbles

Now, P(Picking out 1 white or gray marble)  =

Here, the same experiment is repeated 220 times.

So, the Combined Prediction

= Probability at first attempt  x Number of repetitions

⇒The combined prediction after 220 attempts  = 73

Hence,  total 73 times we can expect white or gray marbles.

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.
