Yes, since 3 times 1.5 is 4 and 2 times 1.5 is 3.
In first trails there are 3 cups of peanuts mixed with 2 cups of raisins.
Therefore ratio of peanut to raisins is
For second trail 4.5 cup of peanuts mixed with 3 cups of raisins
X^2 - 5x + 4
-2x^2 + 10x -8
The square root of 16=4, 4x2=8, x2=8.
Eh, here's my best try for a table:
<u>Like tv</u> <u> don't like tv</u> <u>total</u>
<u>Like reading:</u> 70 10 80
<u>Don't like read</u>. <u>20</u> <u>30</u> <u>50 </u>
<u>total </u> 90 40 130
The percentage of students that like tv as well as reading is- 70 divided by 130 which gives you .538 which in percentage is 53.8%.
The probability of a student that does not prefer to watch tv as also does not like to spend their time reading is 30 over 40 which can be simplified or reduced to 3 over 4. [30/40 reduced to 3/4]
Hope this somehow helped you :)
