Answer:

0.12

Explanations:

What is probability?

Probability is the likelihood or chance that an event will occur. It ca be expressed as:


Probability=(n(E))/(n(S))

where:

n(E) is the expected event

n(S) is the total sample space

If Mrs. Maria's Market buys 75% of eggs from farm A and the rest from farm B, the percentage amount of egg bought from B will be 25% (100-75)

n(S) = 25%

If 3% of the eggs from B are green, hence n(E) = 3%

Determine the required probability

Pr(egg is from farm B) = n(E)/n(S)

Pr(egg is from farm B) = 3/25 = 0.12

Hence the probability that the egg is from farm B is 0.12
