one digit from the number 9,848,778 is written on each of seven cards. What is the probality of drawing a card that shows s 9, 8, or 4?
5/7
two marbles are drawn without replacement from a box with 3 white,2 green, 2 red, and 1 blue marble. Find the probability.
Both are white marbles.
To find the probability of drawing a card that shows a 9, 8, or 4, we need to determine the number of favorable outcomes (cards showing 9, 8, or 4) and divide it by the total number of possible outcomes (total number of cards).
In this case, we know that each card has a different digit from the number 9,848,778. So, there is only one card for each digit (9, 8, 4, 7, 5, 2, 1).
The number of favorable outcomes is the number of cards showing a 9, 8, or 4, which is 3 (one for each digit).
The total number of possible outcomes is the total number of cards, which is 7.
Therefore, the probability of drawing a card that shows a 9, 8, or 4 is 3/7 (three favorable outcomes out of seven total possible outcomes).
