The probability that the card is not yellow is
<em><u>Solution:</u></em>
<em><u>The probability of an event is given as:</u></em>
From given,
A box is filled with 8 blue cards, 8 yellow cards, and 2 green cards
Total number of possible outcomes = 8 + 8 + 2 = 18
Favorable outcome = card is not yellow
Favorable outcome = card is blue or green = 8 + 2 = 10
Therefore,
Thus the probability that the card is not yellow is 5/9
The measure of each angle is 117°
Explanation:
Given that the two angles are (11x-26)° and (7x+26)°
We need to determine the measure of each angle.
<u>Measure of angles:</u>
From the figure, it is obvious that the two angles are vertically opposite angles.
By definition, we know that, the vertically opposite angles are always equal.
To determine the measure of each angle, we shall first find the value of x.
Thus, we have,
Thus, the value of x is 13
Now, substituting in the angle (11x-26)°, we get,
The measure of the angle is 117°
Similarly, substituting in the angle (7x+26)°, we get,
The measure of the angle is 117°
Hence, the measure of each angle is 117°
