Submission Date: 10TH May, 2020

INSTRUCTIONS: Answer all questions

1. Given P(A) = 0.23, P(B) = 0.37 and P(A ? B) = 0.44, find P(B|A). [3 marks]

2. Bags of smokeless fuel are labeled as weighing 100kg, but actual weights are normally

distributed with a mean of 102kg and a standard deviation of 4kg.

(i) What proportion of bags will weigh more than 106kg? [2 marks]

(ii) What proportion of bags will weigh less than 95kg? [2 marks]

(iii) What proportion of bags will weigh between 91kg and 112kg? [3 marks]

3. Consider the frequency distribution below

Class Intervals 0-10 10-20 20-30 30-40 40-50 50-60 60-70 70-80

Frequency (??) 3 8 12 15 18 16 11 5
