There's one unforgivable taboo that transcends just about every branch of mathematics, and that's dividing by zero. Division by zero is undefined, so any fraction with a zero in its denominator is by definition absurd. For what values of x would the denominators on either of those fractions be zero? Those will define the restrictions on your variable.

Answer:

Option A: P(Male or Type B) > P(Male | Type B)

Step-by-step explanation:

Total Female = 85 type A, 12 type B ⇒ 97 Female.

Total Male = 65 type A, 38 type B ⇒ 103 Male

Total type A = 65 + 85 = 150

Total type B = 12 + 38 = 50

total number of people = 97 + 103 = 200

Then the probability would be:

P(Male | Type B) = $\frac{number of male in B}{total number of male}$

= $\frac{38}{103}$

= 0.368

P(Male or Type B) = $\frac{total number of male + (total number of people in B - total number of male in B)}{total number of male}$

= $\frac{103 + (50 - 38)}{200}$

= $\frac{103 + 12}{200}$

= $\frac{115}{200}$

= 0.575

Hence, P(Male or Type B) > P(Male | Type B)

Law Incorporation [45]

First of all, you have to define the value which cannot be changed, in this case it is $250, becuase it is a fixed fee.Then subtract 250 the fee from the amout of money that school can spend = 335
Then divide remaining cash by 8 the price per student : 335:8
and you will get 41.875
As you can see, you have to round the number down to 41, otherwise we would go over the school budget.
Therefore, the number of students is 41.
