A poll is given, showing 45% are in favor of a new building project. If 7 people are chosen at random, what is the probability that exactly 3 of them favor the new building project? Type your answer as a decimal. Be sure to use the appropriate rounding rule. (Hint: Use Stat Crunch) A manufacturing machine has a 10% defect rate. If 6 items are chosen at random, what is the probability that at least one will have a defect? Type your answer as a decimal. Be sure to use the appropriate rounding rule. (Hint: Use Stat Crunch) If a seed is planted, it has a 70% chance of growing into a healthy plant. If 8 seeds are planted, what is the probability that exactly 2 don't grow? Type your answer as a decimal. Be sure to use the appropriate rounding rule. (Hint: Use Stat Crunch)
