Answer:
The correct answer: 0.05404
Step-by-step explanation:
Given:
Binomial distribution = x
n = 10
and p = 0.09
solution:
P(X=x) =1 0Cx*(0.09^x)*((1-0.09)^(10-x)) for x=0,1,2,...,10
So the probability is calculated by the Formula:
P(X>=3) = 1-P(X=0)-P(X=1)-P(X=2)
putting the given values in the formula
= 1-10C0*(0.09^0)*((1-0.09)^(10-0))-...-10C2*(0.09^2)*((1-0.09)^(10-2))
= 0.0540400
Thus, the correct answer: 0.05404

Solutions
We know that a ticket costs £14.50 and it is increased by <span>7% in price. To solve the problem lets use variables.
Let the Variable Y</span><span> = 7% of 14.5
Equation: Y = P% </span>×<span> (X)
Solve for our equation Y
Y = P% </span>×<span> (X)
Y = 7% </span>×<span> 14.5
Now lets convert the percent to a decimal:
Percent = Out of 100
Percent = 7% / 100 = 0.07
Y = 0.07 </span>×<span> 14.5
Y = 1.015
</span><span>
</span>
