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

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

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

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