Find p f b and p e a using the tree diagram
WebHere is a tree diagram for the toss of a coin: There are two "branches" (Heads and Tails) The probability of each branch is written on the branch The outcome is written at the end of the branch We can extend the tree diagram to two tosses of a coin: How do we calculate the overall probabilities? We multiply probabilities along the branches WebUsing the tree diagram, P(B on 2nd R on 1st) = P(R B) = 8 10 8 10. If we are using probabilities, we can label the tree in the following general way. P ( R R ) here means …

WebP(A B) = P(A and B) /P(B) In this case, the only way to find P(B) is to use the law of Total Probability which is just the sum of all the times when the event B occurs, no matter what … WebThe tree diagram is complete, now let's calculate the overall probabilities. Remember that: P (A and B) = P (A) x P (B A) Here is how to do it for the "Sam, Yes" branch: (When we take the 0.6 chance of Sam being coach times the 0.5 chance that Sam will let you be Goalkeeper we end up with an 0.3 chance.) But we are not done yet!

WebSo, the probability that the student doesn't know the answer AND answers correctly is. 1∕3 ∙ 1∕4 = 1∕12. Thereby, the student answers correctly. 2∕3 + 1∕12 = 3∕4 of the time. Now, for the conditional probability we want to view that 3∕4 as if it was 1 whole, which we achieve by multiplying by its reciprocal, namely 4∕3.
