Answer 1

Answer:

percent of the students at Washington Highschool are in Math Club 7% are in Computer Club, and 3% are in both. If a student is selected at random,

membership fees a particular club is rupees 5225 per year if 6754 people are members of that club what will membership fees a particular club is rupees 5225 per year if 6754 people are members of that club what will be the total fee collected by the club the total fee collected by the clubpercent of the students at Washington Highschool are in Math Club 7% are in Computer Club, and 3% are in both. If a student is selected at random,

Answer 2

Four percent of the students at Washington High School are in Math Club 7% are in Computer Club, and 3% are in both. If a student is selected at random, the probability that the student is in Math Club or Computer Club is 2/25

Step-by-step explanation:

4% students are in Math Club

Probability of a student being in the Math Club

$P(M)=\frac{4}{100}$

Similarly,

Probability of a student being in the Computer Club

$P(C)=\frac{7}{100}$

And,

Probability of a student being in the Math Club and Computer Club both

$P(M\cap C)=\frac{3}{100}$

Probability of a student selected randomly, being in a Math Club OR Computer Club $=P(M\cup C)$

We know that

$P(M\cup C)=P(M)+P(C)-P(M\cup C)$

$\implies P(M\cup C)=\frac{4}{100}+\frac{7}{100}-\frac{3}{100}$

$\implies P(M\cup C)=\frac{4+7-3}{100}$

$\implies P(M\cup C)=\frac{8}{100}$

$\implies P(M\cup C)=\frac{2}{25}$

Therefore, the probability that the student is in Math Club or Computer Club is 2/25

Hope this answer is helpful.
