Randomly draw one card. there are 4 blues, 1 red, 3 yellows. If you place the card, predict how many times you will draw a yellow flower card out of 120 draws.
To predict how many times you will draw a yellow flower card out of 120 draws, we need to calculate the probability of drawing a yellow flower card in a single draw.
Out of a total of 8 cards (4 blues + 1 red + 3 yellows), the probability of drawing a yellow flower card is 3/8.
Therefore, if you draw 120 cards, the expected number of times you will draw a yellow flower card can be calculated using the following formula: Expected number of yellow flower card draws = Probability of yellow flower card × Total number of draws = (3/8) × 120 = 45 draws.
So, you can expect to draw a yellow flower card approximately 45 times out of 120 draws.
To determine the probability of drawing a yellow flower card, we need to know the total number of flower cards and the number of yellow flower cards.
In the given scenario, there are a total of 8 flower cards (4 blue + 1 red + 3 yellow). Out of these, 3 are yellow flower cards.
Since we are drawing 120 cards, we can use the concept of probability to estimate the number of times we will draw a yellow flower card.
The probability of drawing a yellow flower card in one draw is given by:
P(Yellow Flower Card) = Number of Yellow Flower Cards / Total Number of Flower Cards
= 3 / 8
To find the expected number of times we will draw a yellow flower card out of 120 draws, we can multiply the probability by 120:
Expected number = P(Yellow Flower Card) * Number of draws
= (3 / 8) * 120
= 45
Therefore, based on probability, we can expect to draw a yellow flower card approximately 45 times out of 120 draws.
