Answer:
Option A is the correct answer.
Step-by-step explanation:
The sum of interior angles of a polygon is given by (n-2) x 180°, where n is the number of sides.
The sum of interior angles will not affect irregularity of polygon, it is same for regular and irregular polygon.
For a pentagon n =5.
Sum of interior angles = (5-2) x 180 = 3 x 180 = 540°
Option A is the correct answer.
Answer:
1/16
Step-by-step explanation:
Four cards numbered (1, 5, 8,9)
Given the sample space S= 4
1.The first selection with replacement
Probability of picking a 9= 1/4
2. Second selection, probability of picking a 9= 1/4
Hence the probability that both cards drawn have the number 9.
Is = (1/4)*(1/4)= 1/16
