If `sqrt(0.04 xx 0.4 xx a)=0.4 xx 0.04 xx sqrt(b)` then find the ratio a/b`.

If \sqrt{0.03 times 0.3 times x} = 0.3 times 0.03 times \sqrt{y} , then find x/y .

In a first order reaction, the concentration of the reactant, decreases from 0.8 M to 0.4 M in 15 minutes. The time taken for the concentration to change form 0.1 M to 0.025 M is :

If P(A) = 0.7, P(B) = 0.4, P(A nn B) = 0.3, then P(A nn B') =

If A and B are events having probabilities P(A) = 0.6, P(B) = 0.4 and P(A nn B) = 0 then the probability that neither A nor B occurs is
