Over 1,000 people try to climb my. Everest every year. Of those who try to climb Everest, 31% succeed. The probability that a climber is at least 60 years old is 0.04. The probability that a climber is at least 60 years old and succeeds in climbing Everest is 0.005. Find the probability of success given the climber is at least 60 years old.

0.125

Step-by-step explanation:

Let S be the event that the climber is successful in climbing Mount Everest and A be the event that the climber is at least 60 years old.

P ( S ) = 0.31

P ( A ) = 0.04

P (S ∩ A ) = 0.005

P ( S | A ) = P ( S ∩ A ) /P ( A ) = 0.005 /0.04

= 0.125

Thus, the required probability is 0.125

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}
