NO LINKS - PLEASE! Create a probability distribution table from this frequency table. Round probabilities to the nearest hundredth.

Hours: 0,1,2,3,4,5,6,7
Frequency: 1,7,13,6,8,5,3,2

b) What is P(x≥4)?
c) what is P(x<3)?

I have to create a probability distribution table:
X
P(x)

b. 2/15

c. 7/15

Step-by-step explanation:

total frequency = 45

X 0 1 2 3 4 5 6 7

P(x) 1/45 7/45 2/45 1/15 4/45 1/9 2/15 7/45

b. P(≥4) = 18/45 = 2/5

c. P(<3) = 21/45 = 7/15

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
