one card is drawn and replaced 200 times. how many times would you expect the red flower card to be drawn? ? times
Answer
Explanation:
Step1: Calculate probability of drawing red - flower card
There are 8 cards in total and 1 red - flower card. The probability $P$ of drawing the red - flower card in a single draw is $P=\frac{1}{8}$.
Step2: Calculate expected number of draws
The number of trials $n = 200$. The expected value $E$ of the number of times the red - flower card is drawn is given by the formula $E=n\times P$. Substitute $n = 200$ and $P=\frac{1}{8}$ into the formula: $E = 200\times\frac{1}{8}=25$.
Answer:
25
