Step-by-step explanation:
Here X the no of children suffering from hookworm treated and recovered is binomial because
a) Each child is independent of the other
b) There are only two outcomes
c) The probability for any child to recover is constant as 90% = 0.9
X is Bin (20,0.9)
a) Prob that all 20 will be cured
=P(X=20)=
b) Prob all but 1 will be cured=
c) Prob exactly 18 will be cured
d) Prob exactly 90% will be cured.

To find the equation, identify the slope and the y-intercept.
The slope is the coefficient to the variable. When you see the word 'per', you know that 2 is the slope, as she is paying 2 dollars per movie. This, in mathematical terms, is represented as 2x.
The y-intercept is the amount she starts off with. She gets 5 for free, so the y-intercept is +5.
The equation is
To solve for c = 50, plug 50 in and subtract 5 from both sides:
m = 22.5
