Answer:
.5
Step-by-step explanation:
Going from WHB to RVM means that we need the number to multiply by to get to RVM, the smaller triangle.
Multiplying by .5 is the same as dividing by 2.
20 x .5 = 10
16 x .5 = 8
12 x .5 = 6
The answer is $2.4, you can find this answer by doing $486 divided by 202.5 which gets you 2.4 and you can check this by multiplying 2.4 by 202.5 which gets you $486 telling you the answer is correct
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:
