a bag contains 7 green marbles and 4 white marbles u sellect a marble at random. what are the odds of picking a green marble?
There are a total of 11 marbles. The odds of picking a green marble are 7 out of 11, or 7/11, which can be simplified to 63.6%.
To find the odds of picking a green marble, we need to determine the number of favorable outcomes (green marbles) and the number of possible outcomes.
Number of green marbles = 7
Number of white marbles = 4
Total number of marbles = Number of green marbles + Number of white marbles
Total number of marbles = 7 + 4 = 11
Therefore, there are a total of 11 marbles in the bag.
The odds of picking a green marble can be calculated by dividing the number of favorable outcomes (green marbles) by the total number of possible outcomes (total marbles).
Odds of picking a green marble = Number of green marbles / Total number of marbles
Odds of picking a green marble = 7 / 11
Hence, the odds of picking a green marble are 7/11 or 7:11.
To calculate the odds of picking a green marble, you need to determine the probability by dividing the number of desired outcomes (green marbles) by the total number of possible outcomes (all marbles).
In this case, there are 7 green marbles and 4 white marbles, making a total of 11 marbles in the bag. Therefore, the probability of picking a green marble can be calculated as follows:
P(green marble) = Number of green marbles / Total number of marbles
= 7 / 11
= 0.6364
So, the odds of picking a green marble are approximately 0.6364 or 63.64%.
