This cannot be the question. You definitely read this wrong. If p(notA)= .75 then P(not A) = .75...
If the question is find P(A), however, then the use the compliment rule
1- P(not A) = P(A)
1-.75 = .25
The correct answer is: 2/5.
Explanation:
First you have to add the following expressions:
Now subtract the above expression from 
:
Hence the correct answer is 2/5.
Answer:
20-4x
Step-by-step explanation:
x = every school day
So first, we need to find a common denominator, make the numbers below the line equal to each other
to do this, we multiply the denominator AND numerator of 4/10 so you can get the equivilent fraction with a denominator of 100
4*10=40
10*10=100
4/10=40/100
now we add the two fractions together and we get
38/100+40/100=
78/100 of a meter
8/ 712 is 72
First see if 8 can go into 71
8 goes into 71 8 times then subtract 71 and 64 since 8*8 is 64
Finally you will get the solution 72 so find how many time 8 can go into 72 and that will be 9.
Answer:89
