I think is A or b go try it am not 100% sure
Answer:
The range of the data is 19.
Step-by-step explanation:
To solve this problem, we must remember that to calculate the range, we subtract the smallest data point in the set from the largest data point. In this case, the largest number is 25 and the smallest number is 6.
Therefore the range is:
25 - 6
= 19
Hope this helps!
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%
