Probability. It has been estimated that about 30% of frozen chickens contain enough salmonella bacteria to cause illness if improperly cooked. A consumer purchases 12 frozen chickens. What is the probability that the consumer will have more than 6 contaminated chickens.

0.0386

Step-by-step explanation:

Given: The probability hat the frozen chickens contain enough salmonella bacteria to cause illness if improperly cooked : p= 0.30

Sample size : n = 12

Let x = Number of contaminated chickens

Here , two outcomes for any chicken (either contaminated or not) , so it follows binomial distribution.

Binomial probability formula:

The probability that the consumer will have more than 6 contaminated chickens :-

 (simplified)

Hence, the required probability = 0.0386

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450
