there are 10 marbles in a bag: 1 blue, 4 yellow, 3 red, and 2 white. if you choose a marble at random, what is the probability that you will NOT choose white?
NOt white: 8/10
The probability would be 8 out of 10.
To find the probability of not choosing a white marble, we first need to determine the total number of marbles in the bag that are not white.
There are 10 marbles in total, and out of those, 2 are white. Therefore, there are 10 - 2 = 8 marbles that are not white.
Next, we can find the probability of choosing a non-white marble by dividing the number of non-white marbles by the total number of marbles.
Probability = Number of non-white marbles / Total number of marbles
Probability = 8 / 10
Simplifying this fraction, we get:
Probability = 4 / 5
Therefore, the probability of not choosing a white marble is 4/5 or 0.8.
