The probability of a blue jay being the next bird papa sees is given by number of blue jays / total number of birds = 59 / (59 + 68 + 12 + 1) = 59 / 140 = 0.4214
Z scores are (age - mean) / std dev

It is x+n-8. I believe that if you put the parentheses it will mean you are multiplying x+n by -8.
We determine the number of cubic yards that James need to order by converting the unit of measurement given in feet to yards. Every yard is composed of 3 feet. Thus, the solution would be,
(180 ft)³ x (1 yd/ 3ft)³ = 6.67 yd³
Thus, James will have to order 6.67 yd³.
