Two and they are both real numbers.
Sample space of rolling 2 dice = {36} outcomes
Getting a sum of 5:
(1+4) or (2+3) or (3+2) or (4+1) = 4 favorable outcomes
P(getting a sum of 5) = 4/36 = 1/9
The expected payoff is :
P(getting a sum of 5) x $9 = (1/9).(9) = 9/9 = $1
Answer:
Hope the below answer is easy to understand
Step-by-step explanation:
1) Given the four angles of a quadrilateral are in the ratio 1:2:3:4
Then Let the angles are x,2x,3x and 4x
We know that total of four angles of a quadrilateral =360 °
∴x+2x+3x+4x=360 °
⇒10x=360 °
⇒x=36 °
hence the measures of angles are 36 ° ,72 ° ,108 ° ,144 °
2) Measure of interior angle of a polygon= 180°.
Sides of the polygon = 7 sides
Therefore,
Interior angle of the polygon having 7 sides = 180/7 = 25 5⁄7°
Positive Test Negative Test
Subject is diabetic 35 3 38
Subject is not diabetic 5 28 33
Total 40 31 71
Probability of getting a subject that is not diabetic, given that the result is negative.
28/31 = 0.903 or 90.3%
The answer is 90.3%.
2.98 as simplified fraction is 149/50
