Answer:
P = 9/16
Step-by-step explanation:
In this question, we are asked to calculate the probability of Mrs Cox picking marbles that are not orange in color.
First, since we are dealing with the color orange and the rest according to the question, we can say that we have only two sets of marbles. The first set is the orange and that contains just 3 orange marbles. The second set contains 5 blue and 4 red marbles making a total of 9.
The probability of not selecting an orange is this; number of non orange marbles/total number of marbles
Total number of marbles is 12. The probability is thus 9/12 or3/4.
Now the probability of selecting a non orange marble twice without replacement is 3/4 * 3/4 = 9/16
Answer:
The quotient is 25.0295566502.
Biconditionals are statements that work both ways.
Some examples:
If it rains, I go out, and if I go out, it must be raining.
This can be stated concisely in mathematical terms as
I go out IF AND ONLY IF it rains.
So looking at the given statements, only the last two work both ways, namely:
If the sun rises in the east, then it is morning, and if it is morning, the sun rises in the east.
Victoria will play outside if and only if the weather is nice.
The answer would be 50 for the question 8 becuase u do the opposite which is 86 divided by 2 and then add seven
