Practicing Success
One number is selected at random from first two hundred positive integers. The probability that it is divisible by 6 or 8, is equal to |
$\frac{29}{100}$ $\frac{33}{100}$ $\frac{43}{100}$ $\frac{1}{4}$ |
$\frac{29}{100}$ |
Total number of integers that are divisible by six $\frac{200}{6}+\frac{200}{36}=38$ Total number of integers that are divisible by eight $\frac{200}{8}+\frac{200}{64}=28$ Total number of integers that are divisible by six as well as by eight i.e. by 24 $\frac{200}{24}=8$ Thus total number of integers that are divisible by 6 or 8 = 38 + 28 – 8 = 58 Thus, required probability = $\frac{58}{200}=\frac{29}{100}$ |
