Devaughn is 9 years younger than sydney. The sum of their ages is 45. What is sydneys age?

Lilit [14]

Sydney's age is 27 years of age. A way to do this is by subtracting 9 from 45 to get 36 and dividing it by 2 which gets you 18 and then adding 9 to that number since 18 is how old Devaughn is

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

notsponge [240]

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:

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