Polynomials are not closed under division. When you divide polynomials it is possible to get quotients with negative exponents or with fractions that have exponents in the denominator, and neither of these could be included in polynomials.

Archie is stranded in a war zone in the land of the Xhosas. His only chance of survival is to reach Sudland, which lies 100 mile

LenaWriter [7]

Answer:

The chances of success for Archie is $P(S|D) = 35\%$

Step-by-step explanation:

From the question we are told that

The distance of Sudland from Xhosas is d = 100 miles

The probability of failure is $P(F) = 0.26$

The probability of choosing the desert route is $P(D) = \frac{1}{40} = 0.025$

The probability of reaching Sudland through the mountain is $P(S|M) =0.75$

Generally the probability of choosing the mountains route is

$P(M) = 1 - P(D)$

$P(M) = 1 - 0.025$

$P(M) = 0.975$

Generally the probability of success is mathematically represented as

$P(S) = 1- P(F)$

$P(S) = 1- 0.26$

$P(S) = 0.74$

Generally the probability of success in reaching Sudland is also mathematically represented as

$P(S) = P(S|M) * P(M) + P(S|D) * P(D)$

=> $P(S|D) = \frac{P(S) - P(S|M) * P(M)}{P(D)}$

substituting values

=> $P(S|D) = \frac{0.74 - 0.75 * 0.975}{0.025}$

=> $P(S|D) = 0.35$

=> $P(S|D) = 35\%$
