Question

Ten bags of wheat flour each marked 5 kg, 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

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

• A.
  $0.5$
• B.
  $0.8$
• C.
  $0.6$
• D.
  $0.7$

Answer 1

The correct option is D

$0.7$
Mark all the weights from the given data set in order to find the probability that the bag chosen at random contains more than 5 kg of Flour.

$\begin{array}{ccccccccccc}\text{Wheat Four (in Kg)}& \text{4.97}& \text{5.05}& \text{5.08}& \text{5.03}& \text{5.00}& \text{5.06}& \text{5.08}& \text{4.98}& \text{5.04}& \text{5.07}\end{array}$

Total such weights out of 10 bags is 7, the required probability will be,

$P=7/10=0.7$

So, the required answer is option (d)
