Question

An integer is chosen from one to 50 what is the probability that it is divisible by 8

Answer 1

Answer:

total number =50

numbers which is divisble by 8= 6

p(E)=6/50

Answer 2

Answer:

$\frac{6}{50}$

Step-by-step explanation:

Let's arrange the integers as follows :

1     2   3   4     5   6    7    8

9   10  11   12   13  14   15   16

17  18  19  20  21  22  23  24

.........................                    32

.........................                    40

.........................                    48

49  50

In other words, there are 6 integers (between 1 to 50) divisible by 8.

A shorter way would be to see the maximum number of times 8 can go into 50,  i.e. 50 ÷ 8 = 6 + a fractional remainder

Thus, P (integer between 1 and 50 is divisible by 8) = $\frac{6}{50}$
