Question

Eleven bags of wheat flour, each marked $5kg$, actually contained the following weights of flour $($in $kg):$
$4.97,5.05,5.08,5.03,5.00,5.06,5.08,4.98,5.04,5.07,5.00$

Find the probability that any of these bags chosen at random contains more than $5kg$ of flour.

• A. $\frac{1}{7}$
• B. $\frac{5}{7}$
• C. $\frac{7}{11}$
• D. $\frac{3}{11}$

Answer 1

Answer: (C)

$\frac{7}{11}$

Total number of bags $=11$
Number of bags containing more than $5kg$ of flour $=7$
The probability that a bag, selected at random, has more than $5kg$ of flour $=\frac{7}{11}$
