To calculate: The value of probability
Answer to Problem 30E
The value of probability
Explanation of Solution
Given information:
There are 6 fish in an aquarium namely a trout, a bass, a perch, a catfish, a walleye and a salmon and three fish at random are drawn.
Formula used:
Probability of an event Eis
Given an event Q , the conditional probability of event A is
Calculation:
Consider the provided information thatthere are 6 fish in an aquarium namely a trout, a bass, a perch, a catfish, a walleye and a salmon and three fish at random are drawn.
The probability of
Let A be an event that removed fish is not walleye and B be an event that removed fish is trout and perch.
Use combination to evaluate the probability, recall that if there are n objects taken r at a time then combination is defined as
Recall that probability of an event Eis
Probability that removed fish is trout and perch,
Probability that removed fish is not walleye but can be trout and perch,
Recall that given an event Q , the conditional probability of event A is
The probability of
Thus, the value of probability
