```							1. Note that 4^x.3^x= 12^xSo the integral is M= ∫12^xdxSubstitute y=12^x so that dy=12^x.ln12 dxSo M= ∫dy/ln12= y/ln12= 12^x/ln122. Number of numbers that are multiples of 2 or 5=Number of multiples of 2 + number of multiples of 5 - number of multiples of 10 = 30 + 12 - 6= 36Hence probability= 36/60= 3/5KINDLY APPROVE :))
