Answer:
Option d.
Step-by-step explanation:
we know that
The graph of a continuous probability distribution is a curve. Probability is represented by area under the curve.
The curve is called the probability density function (abbreviated as pdf).
We use the symbol f(x) to represent the curve
therefore
The probability density function f(x) represents . the height of the function at x.
280 x (1-0.73)
=280 x 0.37
= £103.60
£280 decreased by 73% is <span>£280 multiplied by 37%.
