                                        Ans:Using the inequality$m(b-a)\leq \int_{a}^{b}f(x)dx\leq M(b-a)$$a = \pi , b = 3\pi$$m\leq f(x)\leq M$Max. value of A$2\pi M$Min. value of A$2\pi m$You can easily find the m & M from f(x) (I am not finding b/c f(x) is not clear)Thanks & RegardsJitender SinghIIT DelhiaskIITians Faculty

A man is known to speak the truth 3 out of 4 times. He throws a dice and reports that it is a five. Find the probability that it is actually a 5.

Wrong . I got the ans .
