Question

What is the probability that a randomly selected oar was purchased in the 2010s given that the oar was made from ash wood?Simplify any fractions

Answer 1

P (A) = probability of a car purchased in 2010's

P (B) = probability of the car being made from ash wood

P (A and B) = 4

P (B) = 4 +3 = 7

Conditional probability:

P (B/A) = P (A and B ) / P (B) = 4 / 7 = 0.5714
