Probability = favorable event/total number of events
number of blue=6
total number of possibilities = 15
then P(blue)=6/15 = 2/5 =0.40
W replace it again (so the total number is always 15) & we draw a Red:
P(Red) = 5/15 =1/3 = 0.33
Answer:
153
Step-by-step explanation:
ans.
5x=85
x =85÷5
=17
9x=17x9
=153
Joining midpoints(a line segment MN is formed) tells you that you have a line MN that is 1/2 the length of GH
MN = 1/2 GH
MN = 1/2 (8x + 2)
13 = 1/2 (8x + 2) Multiply both sides by 2
13 * 2 = 8x + 2
26 = 8x + 2 subtract 2 from both sides.
26 - 2 = 8x
24 = 8x Divide by 8
24/8 = x
x = 3

Class boundaries need to be defined so that a point on the boundary is unambiguously placed in one class or the other. With these boundaries, a value of 120 might be placed in the first or the second class—<em>we don't know which</em>.
_____
It is customary to define class boundaries between data values 60.5–120.5, for example, so that no data value can fall on the boundary, or as a semi-open interval [60, 120), so that a boundary value is clearly placed into a specific class.
