If A speaks the truth 75% 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) 0.45 D) 0.482 E) 0.411
Explanation:   Probability that A speaks truth is 75/100= 
<gadget id="calculator">75/100</gadget>
<output>3/4 = around 0.75</output>
0.75   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)=0.75 × 0.6 = 0.45   Answer: 0.45
