Answer:
A- 0.125
B- Success of climbing mount Everest is independent of age.
Step-by-step explanation:
A.
Let x denote success in climbing Mount Everest
Let y denote the climber is at least 60 years old.
Therefore,
P(x) = 0.31
P(y) = 0.04
P( x ∩ y) = 0.005
Probability of success when the climber is at least 60 years old =
P( x ∩ y) ÷ P(y) = 0.005 ÷ 0.04 = 0.125.
B.
The success rate is independent of age as there are both success and failure rates across board on the scale of ages of climbers.
Answer:
Step-by-step explanation:
<h3>Given</h3>
<u>The equation for simple interest:</u>
<u>And values</u>
<h3>Solution</h3>
<u>Interest amount is</u>
<u>Solving for annual interest rate</u>
- 160 = 2000*2r
- 160 = 4000r
- r = 160/4000
- r = 0.04
- 0.04*100% = 4%
Annual interest rate is 4%
