kicyunya [14]

To find the circumference of the circle you need to do dπ. 22×π is 22π. That equals approximately 69.12. Since he walks around it 5 times, 69.12×5 is 345.6 yards.

Suppose that you are taking a T/F exam and you have no idea at all about the answers to the last three questions. You choose ans

podryga [215]

Answer:

0.375, 0.125, 0.5

Step-by-step explanation:

given that you are taking a T/F exam and you have no idea at all about the answers to the last three questions.

Probability for correct guess = 0.5 remains constant for each of the three questions

X - no of questions is binomial with n =3 and p = 0.5

1) the probability that you guessed right on exactly one of the three questions

= P(X=1)

= $3C1(0.5)^3 = 0.375$

2) the probability that you guessed right on zero of the three questions

= $P(X=0)\\= 0.5^3=0.125$

3) the probability that you guessed right on at least two of the questions

= $P(x=3)+P(2)\\= 1-0.5\\=0.5$
