In a freshman high school class of 80 students, 22 students take consumer education, 20 students take french, and 4 students take both. which equation can be used to find the probability, p, that a randomly selected student from this class takes consumer education, french, or both?

First subtract the number of students who take both subjects from the number of students who take Consumer Education

22-4=18

Then,

subtract the number of students who take both subjects from the number of students who take French

20-4=16

Now,

Add 18,16 and 4 and subtract the sum from the total number of students in the class

=80-(18+16+4)

=80-38

=42

Step-by-step explanation:

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)
