Since your second pick is affected by your first pick & your third pick is affected by the first two, it is dependent.

First pick: 18 marbles, 3 are red, so odds are 3/18 = 1/6

Second pick: 17 marbles, 8 are blue, odds are 8/17

Third pick: 16 marbles, 7 are black, odds are 7/16

<span>1/6 * 8/17 * 7/16 = 56/1632 = 7/204 & as mentioned before it's dependent</span>

In a histogram, the proportion of the total area which must be to the left of the median is:

Lana71 [14]

Answer:

A. exactly 0.50

Step-by-step explanation:

We have been given a statement. We are asked to choose the correct option about given statement.

We know that every histogram has 5 points summary.

1st point is known as minimum point, 2nd point is first quartile, 3rd point is median, 4th point is upper quartile and 5th point is maximum point.

In a normal distribution 25% of the data points are to the left 1st quartile, 50% of the data points are to the left of median and 75% of the data points are to the left 2nd quartile.

$50\%=\frac{50}{100}=0.50$

Therefore, exactly 0.50 of the total area which must be to the left of the median.
