Answer: 0.4127
Step-by-step explanation:
The probability formula to find p(F/E):
p(F/E)= N(E n F) / N(E)
p(F/E)= 260 / 630
p(F/E) = 0.4127
Answer:
The probability that the animal chosen is brown-haired is 0.6333.
Step-by-step explanation:
Denote the events as follows:
<em>A</em> : a brown-haired rodent
<em>B</em> : Litter 1
The information provided is:
The probability of selecting any of the two litters is equal, i.e.
According to the law of total probability:
Compute the total probability of event <em>A</em> as follows:
Thus, the probability that the animal chosen is brown-haired is 0.6333.
