Let x= 2.3181818...

then

10x=23.181818... and

1,000x=2,318.1818...

1,000x-10x=2,318.1818...-23.181818...

990x = 2,318 - 23
990x = 2295

x=2295/990

dividing by 5 both numerator and denominator:

x= 459/198

now, x= 198 + 198+ 63

so $x= 2\frac{63}{198}$

Answer: $x= 2\frac{63}{198}$

According to the general equation for conditional probability, if P(A upside down u B)= 5/7 and P(B)=7/8 , what is P(A|B)?

natta225 [31]

$P(A | B) = \frac{P(A \cap B)}{P(B)}$

$P(A|B) = \frac{5/7}{7/8}$

$P(A|B) = \frac{5}{7} \div \frac{7}{8}$

$P(A|B) = \frac{5}{7}\times\frac{8}{7}$

$P(A|B) = \frac{5*8}{7*7}$

$P(A|B) = \frac{40}{49}$
