Question

one candy is drawn and replaced from the bag 80 times. how many times would you expect to draw a purple candy? ? times

Explanation:

Step1: Calculate total number of candies

$10 + 6+4=20$

Step2: Calculate probability of drawing purple candy

The probability $P$ of drawing a purple candy is $\frac{6}{20}=\frac{3}{10}$

Step3: Calculate expected number of times

The number of trials $n = 80$. The expected number of times $E$ of drawing a purple candy is $E=n\times P$. So $E = 80\times\frac{3}{10}=24$

Answer:

24
