there is four reds, two yellows, one blue, and one green
what is the probability of spinning a red or a yellow
To find the probability of spinning a red or a yellow, we need to determine the total number of favorable outcomes (reds and yellows) and divide it by the total number of possible outcomes.
Total number of favorable outcomes: 4 reds + 2 yellows = 6
Total number of possible outcomes: 4 reds + 2 yellows + 1 blue + 1 green = 8
Therefore, the probability of spinning a red or a yellow is 6/8, which simplifies to 3/4 or 0.75.
there are three quaters, one dime, two nickels, and two penneys
what is the probability of not picking out a dime (answer as a reduced fraction in the form a/b
To find the probability of not picking out a dime, we need to determine the number of outcomes that do not involve selecting a dime and divide it by the total number of possible outcomes.
Number of outcomes not involving a dime: 3 quarters + 2 nickels + 2 pennies = 7
Total number of possible outcomes: 3 quarters + 1 dime + 2 nickels + 2 pennies = 8
Therefore, the probability of not picking out a dime is 7/8, which is already in its reduced fraction form.
