When a fair coin is flipped, the probability of its landing heads (H) is 0.500.50 and the probability of its landing tails (T

DedPeter [7]

Answer:

probability (HH) = 1/4 = 0.25

probability (HT) = 1/4 = 0.25

probability (TH) = 1/4 = 0.25

probability (TT) = 1/4 = 0.25

Step-by-step explanation:

given data

probability heads (H) is 0.50

probability heads (T) is 0.50

to find out

the probabilities of each arrangement

solution

when coin toss there are two outcome that is head or tail

and then flip 2 time

possibility are HH HT TH TT

probability (HH) = 1/4 = 0.25

probability (HT) = 1/4 = 0.25

probability (TH) = 1/4 = 0.25

probability (TT) = 1/4 = 0.25

The slope goes through (2,5) and (7,r) and equals 1/3 what is r

myrzilka [38]

The fromula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have

$(2,\ 5);\ (7,\ r),\ m=\dfrac{1}{3}$

Substitute:

$\dfrac{r-5}{7-2}=\dfrac{1}{3}\\\\\dfrac{r-5}{5}=\dfrac{1}{3}\qquad|\text{cross multiply}\\\\3(r-5)=(5)(1)\qquad|\text{use distributive property}\\\\3r-15=5\qquad|\text{add 15 to both sides}\\\\3r=20\qquad|\text{divide both sides by 3}\\\\r=\dfrac{20}{3}$
