If A speaks the truth 70% of the times, B speaks the truth 60% of the times. What is the probability that they tell the truth at the same time
Answers:  A) 0.49  B) 0.48  C) 0.41  D) 0.42  E) 0.411
Explanation:   Probability that A speaks truth is 70/100= 
<gadget id="calculator">70/100</gadget>
<output>7/10 = around 0.7</output>
0.7   Probability that B speaks truth is   60/100= 
<gadget id="calculator">  60/100</gadget>
<output>3/5 = around 0.6</output>
0.6   Since both A and B are independent of each other   So probability of A intersection B is P(A) × P(B)=0.7× 0.6 = 0.42   Answer: 0.42
<result>D</result>
