Answer:
Step-by-step explanation:
Given: The total number of ways of to choose 3 contestants out of 7 (including me and my friend)=35..................> Total outcomes.
Favorable outcomes = 2
Then the probability that me and my friend are both chosen =
Thus , the probability that me and my friend are both chosen =
First solve C
Then make 2 equations to use them
X=22.5

Answer: P(T|B) = 2/3= 0.667
Step-by-step explanation:
Given;
Probability that there is free breakfast at work
P(B) = 0.25
Probability that your coworker lied
P(L) = (1/3)
Probability that your coworker did not lie
P(T) = 1-1/3 = 2/3
Since your coworker already told you there is free breakfast, the condition probability now depends solely on whether he lied or not.
P(T|B) = P(B)P(T)/[P(B)P(T) + P(B)P(L)]
P(T|B) = (0.25×2/3)/[(0.25×2/3 + (0.25×1/3)]
P(T|B) = 2/3= 0.667
Hint: since the coworker already confirmed that there is free breakfast, the probability that there will be free breakfast now depends solely on the whether the co-workers said the truth, which have a probability of 2/3.
i.e P(T|B) = P(T) = 2/3
