or: 0.148
Step-by-step explanation:
Answer:
1/3
Step-by-step explanation:
Let A be the event that you grab the fair coin and B be the event that you toss a tail.
P(A) is the probability that you grab the fair coin, which is 1/3
P(B) is the probability that you toss a tail, which is 1/2
P(B|A) is the probability that you toss a tail, given that you grab a fair coin, which is 1/2
P(A|B) is the probability that you grab the fair coin, given that you toss a tail, which we are looking for.
Using Bayes probability theorem we have:

Solve: 4x + 3 =2x +9
4x + 3 = 2x + 9
-2x -2x
2x + 3 = 9
-3 -3
2x = 6
2x/2 = 6/2
x = 3
Answer would be : x = 3
