Answer:
1 / 36
Step-by-step explanation:
Given that :
Number of faces on a number cube = 6
Sample space kn two number faces = 6² = 36
Probability that sum of a roll is 12 :
Probability = number required outcome / Total possible outcomes
Number of Required outcome = 1 (sum of 12)
Total possible outcomes = 6² =36
P(sum of 12) = 1 /36
Answer:
82.88%
Step-by-step explanation:
Given that:
Mean (μ) = 16.7 pounds
Standard deviation (σ) = 3.8 pounds
Number of pounds eaten = 11.5 = x
P(11.5 ≥ x ≤11.5)
P(x ≤ 11.5) :
Zscore = (x - μ) / σ
Zscore = (11.5 - 16.7) / 3.8
Zscore = - 5. 2 / 3.8
Zscore = −1.368421
P(Z ≤ - 1.3684) = 0.085593 (Z probability calculator)
P(x ≥ 11.5) ;
Zscore = (x - μ) / σ
Zscore = (11.5 - 16.7) / 3.8
Zscore = - 5. 2 / 3.8
Zscore = −1.368421
P(Z ≥ - 1.3684) = 0.91441 (Z probability calculator)
P(Z ≥ - 1.3684) - P(Z ≤ - 1.3684)
0.91441 - 0.085593 = 0.828817
0.828817 * 100% = 82.88%
An irrational number.
Example: Pi. Pi doesn’t have an ending as far as we know, so it cannot be written as a fraction.
