Answer:
The probability is 10/121
Step-by-step explanation:
In this question, we are tasked with calculating probability.
The probability to be calculated is that we have an ordered selection of picking a red marble after which we pick a yellow marble.
Firstly let us know the total number of marbles we have. That will be 4 + 5 + 2 = 11 marbles
Probability of picking a red marble will be 5/11 while the probability of picking a yellow marble will be 2/11
Now, the probability of picking a red marble before a yellow marble will be mathematically equal to; P(r) * P(y) = 5/11 * 2/11 = 10/121
Answer:
First, I would check and see if she was correct. If she wasnt, I would simply show her why she was incorrect. If I was to accidently short her, I would give her the money and move on with my day. if she refused to leave after showing her that I gave her the correct amount of money, she would probably call for the manager. I'd get the manager, explain what happened, and the annoying customer would most likely get kicked out of the store.
(P.S: sorry if it was a little confusing lol)
Answer:
The pack of 12 pencils for 298 is better as it has a lower unit price.
Step-by-step explanation:
To be able to find the answer, you have to calculate the unit price for each brand by dividing the price of the pack by the number of pencils in the pack.
-298/12=24.83
-499/18=27.72
According to this, the answer is that the pack of 12 pencils for 298 is better as it has a lower unit price.
Area of rectangle = l × b
l = 70cm
b = 8cm
Area = 70 × 8 = 560cm²
Area of rectangle = l × b
l = 78cm
b = 15cm
Area = 78 × 75 = 1170cm²
