Answer:
P = 1/2 = 0.5
Step-by-step explanation:
Total amount of cans = 100
Cans of cola = 34
Cans of orange soda = 50
Cans of ginger ale = 12
Cans of root beer = 4
Probability of selecting
- a can of cola = 34/100 = 0.34
- a can of orange soda = 50/100 = 0.5
- a can of ginger ale = 12/100 = 0.12
- a can of root beer = 4/100 = 0.04
Since we are asked the probability that the can selected is a root beer, cola, or ginger ale, we need to add together the probabilities of each.
P = 0.04 + 0.34 + 0.12 = 0.5 = 1/2
The answer is shown below:
Rectangle JKLM has an area of 36 square centimeters. The side is at least 4 centimeters long. Prove: KL is 9 centimeters. Assume that a. "KL > 0". Then the area of rectangle JKLM is greater than b.) "40 centimeters² ", which contradicts the given information that c. the area is 40 centimeters². So the assumption must be false. Therefore, d.) "KL <= 10".
Answer:
yes it's correct good luck
Answer:
0.0492
Step-by-step explanation:
Based on the tree diagram we need to tell the the probability that the test for lice returns a false positive. False positive means that the student has no lice but still the test shows a positive result.
So for this we have to first look for the branch, from the starting node, which shows that student has no lice. From the starting point, the upper branch represents the students that have lice and lower branch represents the students who have no lice. So, we will consider the lower branch with probability mentioned as 0.82
Now, the lower branch is divided into two branches further. We have to look for the branch which shows positive test result. This would be the upper branch with probability mentioned as 0.06.
The overall probability of this event is mentioned at the end of the branch which is 0.0492
This is the probability of the combined event: Student has no lice but tests shows positive result which is the False positive.
Thus, the probability that the test for lice returns a false positive is 0.0492
Answer:
the answer is false because 3 is multiplied with 5 on the right side
Then, when substitute any number , there remain difference
