What is the probability of picking green marbles?
The probability of selecting a green marble at random from a jar that contains only green, white and yellow marbles is 0.
What is the probability of picking red marbles?
Note that there are 16 total marbles. A is simply a set of sequential events. On the first, you have 10/16 chances to draw a red. Supposing this red is not replaced, the chance of drawing a second red will be 9/15; therefore, the probability of A is (10/16) * (9/15) = 0.375.
What is the probability of picking 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. It wants you to try and do the whole big problem at once, which can be difficult.
What is the probability of picking a blue marble putting it back in the bag then picking a red marble?
The probability of the first marble being red is 943. After returning this marble to the bag, the probability of the second marble being blue is 1143. So the probability picking a red marble, and then a blue marble is 943⋅1143≈0.054.
What is probability of picking blue marbles?
When you draw the first marble, there are 10 marbles in the jar of which 6 are blue, so your probability of drawing a blue one is 6/10 (60 percent) or 3/5.
What is the probability that the marble will be red or green?
0.8
The probability that the marble is either red or green is 0.8.
What’s the probability of picking a yellow marble?
That is roughly 37.5% chance of picking a yellow marble leaving a 62.5% chance of picking a non yellow marble (those add up to 100%) so low probability of picking a yellow marble
How to find the probability of multiple of 2?
So you have to find the probability of multiple of 2, multiple of 3 and multiple of 6. Add the probability of multiple of 2 and 3, then subtract the probability of multiple of 6. When you find the multiple of 2 and 3, you are counting multiple of 6 twice.
How to find the probability of a visit?
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.
