one candy is drawn and replaced from the bag 80 times. how many times would you expect to draw a purple candy? ? times
Answer
Explanation:
Step1: Calculate total candies
$10 + 6+4=20$
Step2: Calculate probability of purple candy
The probability $P$ of drawing a purple - candy is $\frac{6}{20}=\frac{3}{10}$
Step3: Calculate expected number of draws
The number of trials $n = 80$. The expected value $E=n\times P$. So $E = 80\times\frac{3}{10}=24$
Answer:
24
