Which expression represents the probability of rolling a 5 exactly three times in ten rolls of a number cube with six sides?

2 answers:

8 0

I'm not sure what the options are as this appears to be a multiple choice question, but this probability is as follows:
$P(X=3)={10\choose3}(\frac{1}{6})^3(\frac{5}{6})^7$

Area of the trapezoid:
$\frac{12.8 + 4.2}{2} (4.9) = 41.65 cm^2$

Area of the rectangle:
4.2 x 3.1 = 13.02 cm^2

Area of each quarter circle:
$\frac{ \pi (3.1)^{2} }{4} = 7.54 cm^2$

We have two quarter circles:
7.54 + 7.54 = 15.08

41.65 + 13.02 + 15.08 = 69.75 cm^2
