Applying the trapezium midsegment theorem, the length of XY is: 30.
<h3>What is the Trapezium Midsegment Theorem?</h3>
- Trapezium midsegment theorem states that the length of the median that joins two sides of a trapezium equals half the sum of he two bases of the trapezium.
Thus:
Let XY = x
WZ = 4/3(x)
DE = 35 (given)
Thus:
35 = 1/2(4/3x + x)
2(35) = 7x/3
70 = 7x/3
3(70) = 7x
210 = 7x
x = 30
x = XY = 30
Therefore, applying the trapezium midsegment theorem, the length of XY is: 30.

The probability of not drawing a black marble is 4/5
The probability of drawing a red marble is 3/10
<h3>What are the probabilities?</h3>
Probability determines the odds of the occurrence of a random event. The probability the event occurs is 1 and the probability that the event does not occur is 0.
Probability of not drawing a black marble = total marbles that are not black / total number of marbles
(5 + 3) / (5 + 3 + 2) = 8/10 = 4/5
The probability of drawing a red marble = total number of red marbles / total number of marbles
= 3/10
