A certain three-digit number equals fifteen times the sum of its digits. if its digits are reversed, the resulting number exceed

lara31 [8.8K]

If the digits are a, b and c, the number n is 100a+10b+c

Here are the equations:

a number equals fifteen times the sum of its digits:

100a+10b+c = 15(a+b+c)

if its digits are reversed, the resulting number exceeds n by 396:

100a+10b+c+396 = 100c+10b+a

the one’s digit is one larger than the sum of the other two:

a+b+1 = c

Solving it gives you a=1, b=3, c=5, the number is 135.

O COUNTING AND PROBABILITY

valina [46]

Answer:

a. $Odds = \frac{3}{7}$

b. $Odds = \frac{7}{3}$

Step-by-step explanation:

Given

$n(Black) = 7$

$n(Grey) = 2$

$n(White) = 1$

$n(Total) = 10$

Solving (a): Odds against winning

Since, the arrow must stop at black, then

The odds against winning is calculated as thus:

$Odds = \frac{n(Total) - n(Black)}{n(Black)}$

$Odds = \frac{10 - 7}{7}$

$Odds = \frac{3}{7}$

Solving (b): Odds in favor of winning

Since, the arrow must stop at black, then

The odds is calculated as thus:

$Odds = \frac{n(Black)}{n(Total) - n(Black)}$

$Odds = \frac{7}{10 - 7}$

$Odds = \frac{7}{3}$
