<span>This is a matter of knowing the formulas involving the binomial distribution:
Mean = n*p = 125*0.46 = 57.5
Variance = n*p*(1-p) = 125*0.46*(1-0.46) = 125*0.46*0.54 = 31.05
Standard Deviation = sqrt(Variance) = sqrt(31.05) = 5.572252686</span>
3x+x=96
(4x=96)/4
x=24
3(24)=72
Hector is 24 and his grandma is 72.
hope this helps!
