Question

According to the manufacturer, about 14% of candy-coated milk chocolates in a package of Charlie's Chocolates are yellow. What is the probability that the first yellow candy chosen from the bag will be, at LEAST, the fourth candy chosen overall?

Answer 1

Answer: 0.6361 is the answer.

Explanation:

I got the answer correct on the quiz.

Answer 2

0.089

Explanation:

The probability of the candy chosen is yellow is:

• 14% or 0.14

The probability of the candy chosen not yellow is:

• 100%-14%= 86% or 0.86

The number of trials is four, three of them being non-yellow and 1 being yellow.

The probability is the combination of four events and is calculated as:

• P= (0.86)^3*0.14 ≈0.089

So the answer is 0.089
