Answer:
See below in bold.
Step-by-step explanation:
For the fair coin Prob(head) = 1/2 and Prob(Tail) = 1/2.
For the biased coin it is Prob(head) = 2/3 and Prob(Tail) = 1/3.
a) Prob(2 heads) = 1/2 * 2/3 = 1/3.
b) Prob(2 tails) = 1/2 * 1/3 = 1/6.
c) Prob(1 head ) = Prob(H T or T H) = 1/2 * 1/3 + 1/2 * 2/3) = 1/6+1/3 = 1/2.
d) Prob (at least one head) = prob (HH or TH or HT) = 1/3 + 1/2 =<em> </em>5/6.
Hii I believe your option would be D. I hope it helps :)
Answer: 3,200in^2
Step-by-step explanation: multiply 80 and 40
the First we need to choose two points in the graph
(0,6)=(t1,w1)
(1,7)=(t2,w2)
the variables are t and w
then we can calculate the slope

the equation of W is
where
m=1 ---> slope
b=6 ---> y-intercept

the answers are
W=t+6
slope of the function 1
the answer is the third option
You would do
51-5= 46
then you would divide
46/2= 23
so Susan is
23+5=28
Susan is 28 years old and her sister is 23
28+23=51
