Step-by-step explanation:
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:
16 ounces = 1 pound
meaning 2.5 pounds is added to the skull, 602.5 pounds.
-4y + 30z - 15y - 3z
-19y +27z
<span>We will call A to the number of hours traveled by Annie and B the number of hours travelled by Brian. Then Annie traveled 5 times plus 2 hours than Brian, that is
A = 5 * B + 2. And the total number traveled by both of them was 20, so: A + B = 20
Next step is solve both equations putting value of A in the second equation:
5 * B + 2 + B = 20 that is the same than:
6 * B = 18 and:
B = 3 then:
A = 5 * 3 +2
A = 17
The solution is Annie traveled 17 hours and Brian only traveled 3 hours.</span>
