4Okay, so here's how you will do the problem.
first lets find out how many marbles there are in total. At first, there are 16 marbles. (6 yellow + 10 blue)
knowing this
P(Yellow) = 6/16. that simplifies to 3/8
P(Blue) = 10/16. that simplifies to 5/8
We can tell these are correct because when added together the probabilities equal 1 (meaning there's no missing probabilities)
Now, 2 yellow marbles and 3 blue marbles are removed.
this means there are now 4 yellow marbles and 7 blue marbles. this brings the total amount of outcomes is 11.
Now
P(yellow) = 4/11
P(blue = 7/11
we can cross multiply or find out the decimal values and compare to find out if the two are equal
3/8.× 4/11
33........32
5/8 × 7/11
55....56
We will come back to what this shows us in a moment
yellow - .375 (3/8) > .36 repeated
blue - .625 (5/8) < .63 repeated
Both methods show that the probability CHANGED. So, YES the probabilities were affected.
in method one, the cross multiplying show that yellow probability goes down and blue probability goes up. Using the decimals shows the same
hope this helps!
The direction of the vector is - 21.8 N of E , Option B is the answer.
<h3>What is a Vector ?</h3>
A vector is an object with both magnitude and direction.
A vector is shown in the graph.
To determine the direction , The angle needs to be determined
The slope of the vector will give the direction of the vector
The vector starts from the point (1 , 1)
Another point on the vector (-4 , 3)
slope = -2 /5
It is making angle x with the line y = 1
tan x = -2 /5
x = - 21.8 N of E.
Therefore the direction of the vector is - 21.8 N of E , Option B is the answer.
