Answer:
6.5 × 10¹⁵/ cm³
Explanation:
Thinking process:
The relation 
With the expression Ef - Ei = 0.36 × 1.6 × 10⁻¹⁹
and ni = 1.5 × 10¹⁰
Temperature, T = 300 K
K = 1.38 × 10⁻²³
This generates N₀ = 1.654 × 10¹⁶ per cube
Now, there are 10¹⁶ per cubic centimeter
Hence,

Answer:
1. 0.50
2. 0.75
3. 0.65
Explanation:
1. For the bid being successful with a 50-50 chance, we have the probability:
50/(50 + 50) = 50 / 100 = 0.50
2. Given the request for additional info:
Probability = probability of request and successful / probability of successful
= 75 / 100 = 0.75
3. We will evaluate the probability of being successful given its request
We will use the Bayesian theorem
= [P(request | successful) * P(successful)] / [P(request | successful) * P(successful) + P(request | unsuccessful) * P(unsuccessful)]
= ( 0.75 * 0.5) / (0.75 * 0.5 + 0.4 * 0.5)
= 0.65
