Step-by-step explanation:
a) The probability that the ball drawn is red is approximately 0.4615
b) If the ball drawn is red, the probability that it came from urn A is approximately 0.7222.
To calculate the probabilities, we can use the following formulas:
a) Probability of drawing a red ball (R):
P(R) = (Number of red balls) / (Total number of balls)
b) Probability that the ball came from urn A given that it is red (R|A):
P(R|A) = (Probability of drawing a red ball from urn A) / (Probability of drawing a red ball)
Let's calculate both probabilities:
a) Probability of drawing a red ball:
Total number of red balls = 5 (Urn A) + 4 (Urn B) + 3 (Urn C) = 12
Total number of balls = 5 (Urn A) + 7 (Urn A) + 4 (Urn B) + 3 (Urn B) + 3 (Urn C) + 4 (Urn C) = 26
P(R) = 12 / 26 ≈ 0.4615
b) Probability that the ball came from urn A given that it is red:
P(R|A) = (Probability of drawing a red ball from urn A) / (Probability of drawing a red ball)
P(R|A) = (5 / 12) / (12 / 26) = (5 / 12) * (26 / 12) ≈ 0.7222
