Probability that both roads from a to b are blocked is the product of the individual probabilities, i.e.
P(~ab)=0.25*0.25=0.0625
Similarly
P(~bc)=0.25*0.25=0.0625
Probability that EITHER one or both of ab and bc are blocked is the sum of the probabilities:
P(~ab ∪ ~bc)=0.0625+0.0625=0.125
(recall that one cannot travel from a to c if either ab or bc is blocked.)

Therefore the probability that there exists an open route from a to c
= P(ac) = 1-P(~ab ∪ ~bc)
= 1 - 0.125
=0.875

aleksandr82 [10.1K]
15.25 divided by 100= 0.1525 times 15 = 2.2875 then round to $2.29 (2.29 is the tip) 2.29 + 15.25 = $17.54 would be the total cost!

(- 1 + √3)/2

rationalise the denominator by multiplying the numerator/denominator by the conjugate of the denominator.

the conjugate of 1 + √3 is 1 - √3

(1 - √3)/(1 + √3)(1 - √3) = (1 - √3)/( 1² - (√3)²) = (1 - √3)/(1 - 3) = (1 - √3)/(- 2)

multiply numerator/denominator by (- 1)

=(-1 +√3)/2
