What is the probability of drawing one marble?
The probability of drawing a red marble = 2/5. The probability of drawing a blue marble is now = 1/4. The probability of drawing a red marble = 2/5.
How do you find the probability of a marble?
If there are three red marbles and two blue marbles, then the probability of drawing any red marble is the number of outcomes in the event ” red,” which is equal to three, divided by the total number of outcomes, 5, or 3/5 = 0.6.
What are the chances of drawing 2 blue marbles?
The chances of drawing a blue marble are 4/9. Therefore, the chance that both marbles drawn are blue is the chance that the first one is blue times the chance that the second one is blue. Remember, math is always trying to trick you.
What is the probability of choosing a marble that is not blue?
A bag contains 7 red marbles, 2 blue marbles, and 1 green marble. If a marble is selected at random, what is the probability of choosing a marble that is not blue? 7 red marbles plus 1 green marble = 8/10 = answer = 4/5 A bag contains 6 red marbles, 3 white marbles, and 7 blue marbles.
How many marbles are in a box of marbles?
Example 8 A box contains 3 blue, 2 white, and 4 red marbles. If a marble is drawn at random from the box, what is the probability that it will be (i) white?
What is the probability of 136 visitors to a costume shop?
Well, I’m not great at this stuff, but I can at least try. There are 136 visitors, because 97 + 26 + 13 = 136. 13 visitors purchased more than one costume, so the probability is 13/136. I personally don’t understand the last part, so I can’t help you there.
Can probability be expressed as a Decima?
Since the maximum probability is 1 (or 100\%), all probabilities could be expressed as a decima. Decimals may require rounding. As long as the decimal is less than 1, it is one of the ways to express probability. Comment on David Severin’s post “Probability can be expres…”
