If we know that Pedro bought 1 
pounds of red sand, and 5 
pounds of brown sand, and they both cost $4.60, then we just have to add the individual amounts of sand, since they cost the same.
So Pedro bought
lbs of sand overall. Now, we just need to multiply the cost per pound by the total amount of sand he bought.
Pedro spent $31.05 on sand, which is answer choice B.

Answer:
0.625
Step-by-step explanation:
Given that {A1, A2} be a partition of a sample space and let B be any event. State and prove the Law of Total Probability as it applies to the partition {A1, A2} and the event B.
Since A1 and A2 are mutually exclusive and exhaustive, we can say
b) P(B) = P(A1B)+P(A2B)
Selecting any one coin is having probability 0.50. and A1, A2 are events that the coins show heads.
c) Using Bayes theorem
conditional probability that it wasthe biased coin
=
d) Given that the chosen coin flips tails,the conditional probability that it was the biased coin=
