1. Express the indicated degree of likelihood as a probability value.
"There is a 40% chance of rain."
2. Find the indicated probability
A bag contain 6 red marbles, 3 blue marbles, and 7 green marbles. If a marble is randomly selected from the bag, what is the probability that it is blue. Is the answer 3/16?
1) seems to me, "a 40% chance of rain" is already expressed as a probability value.
2) I get 3/16 also.
1. To express the indicated degree of likelihood as a probability value, we need to convert the percentage into a decimal.
In this case, the statement "There is a 40% chance of rain" means that there is a 40 out of 100 chance of rain. To convert this to a decimal, we divide 40 by 100, which gives us 0.4. Therefore, the probability value is 0.4.
2. To find the probability of selecting a blue marble from the bag, we need to calculate the ratio of the number of favorable outcomes (blue marbles) to the total number of possible outcomes (total number of marbles in the bag).
Given that there are 6 red marbles, 3 blue marbles, and 7 green marbles, the total number of marbles in the bag is 6 + 3 + 7 = 16.
The number of blue marbles is 3, so the probability of selecting a blue marble can be calculated as follows:
Probability = Number of favorable outcomes / Total number of possible outcomes
Probability = 3 / 16
Hence, the answer is indeed 3/16.
