To calculate: The value of probability
Answer to Problem 29E
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 a salmon and B be an event that removed fish is a bass.
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 a bass,
Probability that removed fish is salmon and bass,
Recall that given an event Q , the conditional probability of event A is
The probability of
Thus, the value of probability
