7 times 2 will be 14 and 3 times 2 is 6. So you need to add 14 plus 6 and you get 20 :) Hope you enjoy!
Answer:
Probability that event will have both red marbles will be 2.3% or 0.023.
Step-by-step explanation:
Given:
Total red marbles=5
Total blue marbles=25
Total number of marbles =30
To Find:
The probability that both are red without replacement of marbles.
Solution:
Now
Total sample space is 30 and total red marbles are 5
For a event that getting red marble probability is ,
=Total red marbles /total marbles.
=5/30
=1/6
So probability if getting red marble is 1/6
<em>Now for second chance there will be 4 red marbles remaining and 29 total marbles so,</em>
In second chance probability if getting red marble will be
=total red marbles present/total marbles remaining
=4/29
Now ,
The required probability will be getting both at a time
i.e probability getting red AND red marble so here AND operator which means multiple both the probability.
Probability both will have red =1/6*4/29
=4/(29*6)=2/(29*3)
=0.022988
=0.023
=2.3 %
Answer:
The bigger engine is about 235.5 cubic centimeters larger than the smaller engine.
Step-by-step explanation:
<u>We need the answer in cubic centimeters. So let's convert 350 cubic inches to cubic centimeters. We will do it unit conversion way (long way). </u>
We will write cubic inches as three <em>"inches" side-by-side:</em>
<em></em>
This way, we can multiply this by the ratio of <u>centimeters-to-inches</u> [2.54 cm = 1 inch]<u>,</u> so that the units cancel and we have cubic centimeters (what we desire).
<u>So, we can cancel the three "inches" top and bottom thus we have the answer in centimeters cubed. And the value is:</u>
So 350 cubic inches is approximately 5735.5 cubic centimeters (rounded to 1 decimal place).
This is larger than 5500 cubic centimeters engine. <em>By how much?</em>
cubic centimeters.
The bigger engine is about 235.5 cubic centimeters larger than the smaller engine.
