Do anyone have like a formula sheet or a summary for all the formulas and equations we took in the entire course ? Something to refer to when revising ? ( Pure Maths 1 and 3 , Stats 1 and Mechanics 1 )

quick question. If a body is about to topple (without sliding), what is the relationship b/w F and μR ? Should it be F<μR or opposite
Also if the body is about to slide (without toppling) should it be F<μR or something else?

The random variable X has a normal distribution with mean μ and standard deviation σ.
(i) if 2μ = 1.5 σ, find P(X<3μ).
(ii) if P(X>1/3μ ) =0.7257, express μ in terms of σ.
