Answer:
0.29125 or 29.125%
Step-by-step explanation:
For the five fair coins, the probability of coming up head when flipped is 0.5, so for two flips: 0.5*0.5 = 0.25, for each of these coins. So, the probability to take on of them is 5/8, and the probability of coming up with head: (5/8)*0.25 = 0.15625.
For the unfair coins, the probability of coming up with heads is 0.6, so for two flips: 0.6*0.6 = 0.36 for each unfair coins. The probability to chose one of them is 3/8, and the probability of coming up with head: (3/8)*0.36 = 0.135.
These probabilities are dependent, so to have the total probability we must sum them:
P = 0.15625 + 0.135
P = 0.29125 or
P = 0.29125 x 100% = 29.125%

0.58 is ya answer!
The elevator can carry the adults with average mass of 80 kg.
Step-by-step explanation:
Given
Capacity to weight that can be hold by elevator = 2500 pounds
Average mass of one adult = 80 kg
Average mass of 10 adults = 80*10 = 800kg
We need to have the weights in same unit in order to determine whether the elevator can carry the adults or not.
We will convert the weight of 10 adults into pounds.
1 kg = 2.205 pounds
800 kg = 800*2.205 = 1764 pounds
Therefore,
1764 pounds < 2500 pounds
The elevator can carry the adults with average mass of 80 kg.
