Which fraction is closest to 1? 5/6, 11/20 or -9/10

2 answers:

7 0

If you change all the fractions to a common denominator then it will be easier to compare fractions. in this case the greatest common denominator is 60. you can find the the greatest common denominator by finding the greatest common factor of the numbers

5/6 = 50/60
11/20 = 33/60
-9/10 = -54/60

by doing this we can see that 5/6 is the closest fraction to 1. if you are confused on the -9/10 that is the closest to -1 not 1.

Suppose a box contains a double-headed coin, a double-tailed coin, and a conventional coin. A coin is picked at random and flipp

Answer:

P(D|A)=0.666

Step-by-step explanation:

We will use the tree diagram to understand these probabilities that is attached to the bottom of this answer.

Since there are three coins in the box, the probability of taking one in particular (the double-headed one, which is event D) is one third, which is equal to 0.333

Since the coin showed heads, the probability of it being a double-tailed coin is zero.

The Bayes theorem says that P(D|A) is the multiplication of P(D) and P(A), divided the probability of A happening by any means, happening D or not, which is the sum of all probabilities of A happening:

$P(D|A)=\frac{P(D)*P(A_1)}{P(D)*P(A_1)+P(E)*P(A_2)} =\frac{0.333*1}{0.333*1+0.333*0.5}=0.666$
