a bag of 25 marbles contains 8 red marbles.if one marble is picked from the bag,what is the probability that it is red in percent?
My answer is 32% am i right?
Right.
To find the probability of picking a red marble from the bag, you need to divide the number of favorable outcomes (picking a red marble) by the total number of possible outcomes (picking any marble).
In this case, there are 8 red marbles out of a total of 25 marbles. So the probability can be calculated as follows:
Probability of picking a red marble = (Number of red marbles) / (Total number of marbles) = 8 / 25
To express this probability as a percentage, you need to multiply it by 100:
Probability in percent = (8 / 25) * 100 = 32%
Therefore, your answer of 32% is correct.
