Among 35 students in a class, 20 of them earned A's on the midterm exam, 13 earned A's on the nal exam, and 12 did not earn A's

enyata [817]

Answer:

The correct answer is " $\frac{2}{7}$ ".

Step-by-step explanation:

According to the question,

Number of students,

= 35

A ! mid term A,

$n(A) = 20$

B : final A,

$n(B) = 13$

Didn't start,

$n(A^c \cap B^c) = 12$

Now,

⇒ $n(A \cup B)=35-12$

$=23$

then,

⇒ $n(A \cup B)=20+13-23$

$=10$

hence,

The probability will be:

⇒ $P(A \cap B)=\frac{10}{35}$

⇒ $=\frac{2}{7}$

How many 4 1<br> 2<br> inch strips can be made from 45 inches of shipping tape?

bezimeni [28]

Just divide the 45 by the 4½

thus $\bf 45\div 4\frac{1}{2}\iff \cfrac{45}{4\frac{1}{2}}\implies \cfrac{\frac{45}{1}}{\frac{4\cdot 2+1}{2}}\implies \cfrac{\frac{45}{1}}{\frac{9}{2}}\implies \cfrac{45}{1}\times \cfrac{2}{9}\implies \cfrac{45\times 2}{1\times 9}$
