• # question_answer A student has 60% chance of passing in English and 54% chance of passing in both English and Maths. What is the percentage probability that he will fail in maths? A) 12                                B) 36C) 4                                 D) 10

Let probability of passing in English and Math are P & P (B). Then, here $P\,\,(A)=60%$ $P\,\,(A\cap B)=54%$ $P\,\,(A\cap B)=P\,\,(A)\times P\,\,(B)$ $54=60\times P\,\,(B)$ $\Rightarrow$   $P\,\,(B)=0.9$ $P(B)=90%$ Hence, the % probability that he will fail in Maths $=P\,\,(B)$ $=100-90$ = 10%
