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

<h3>Total 73 times we can expect white or gray marbles.</h3>

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) = $\frac{\textrm{Total Favorable outcomes}}{\textrm{Total Outcomes}} = \frac{11}{33} = (\frac{1}{3})$

Here, the same experiment is repeated 220 times.

So, the Combined Prediction

= Probability at first attempt x Number of repetitions

$= (\frac{1}{3} ) \times 220 = \frac{220}{3} = 73.33 \approx 73$

⇒The combined prediction after 220 attempts = 73

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

The maximum number of shrubs (x) = a(area) divided by 15.9

a(area)=37.1*15
37.1*15= 556.5
556.5/15.9=x
556.5/15.9=35
35=x
