A stack of index cards contains 3 yellow cards, 4 green cards, and 1 red card. Alexa will pull 3 cards from the stack, one at a time without looking. She will not replace a card before pulling the next card. What is the probability that she will draw a yellow card, then a green card, then a red card? Show all steps. *

To find the experimental probability that John will roll a number 3 on the next roll, you need to divide the number of times John rolled a 3 by the total number of rolls. In this case, John rolled a 3 six times out of 20 rolls. So the experimental probability is 6/20, which can be simplified to 3/10. Therefore, the answer is 3/10.
To predict the number of times a student will be a girl in Mrs. Laterrade's LL class, you can use the concept of probability. Since there are 12 girls and 8 boys in the class, the probability of randomly selecting a girl is 12/(12+8) = 12/20 = 3/5. To predict the number of times a student will be a girl in 180 school days, you can multiply the probability by the total number of days, which gives you (3/5) * 180 = 108. Therefore, the best prediction for the number of times a student will be a girl is 108.
To find the number of possible outcomes when tossing a coin and spinning a spinner with 4 equal sections, you can multiply the number of outcomes for each individual event. The coin toss has 2 possible outcomes (heads or tails), and the spinner has 4 possible outcomes (numbers 1-4). Multiplying these gives you 2 * 4 = 8 possible outcomes.
To find the probability of drawing a yellow card, then a green card, then a red card from a stack of index cards, you need to calculate the probability of each event happening and multiply them together.
To start, there are 8 cards in total (3 yellow, 4 green, and 1 red). If Alexa pulls cards without replacement, the total number of cards decreases with each draw.
First, the probability of drawing a yellow card on the first draw is 3 yellow cards out of 8 total cards. So the probability is 3/8.
Then, on the second draw, there are now 7 cards left with 2 yellow cards and 4 green cards. So the probability of drawing a green card is 4/7.
Finally, on the third draw, there are 6 cards left with 1 yellow card, 4 green cards, and 1 red card. So the probability of drawing a red card is 1/6.
To find the overall probability, you multiply the probabilities of each event together: (3/8) * (4/7) * (1/6) = 12/336 = 1/28.
Therefore, the probability that Alexa will draw a yellow card, then a green card, then a red card is 1/28.
