Calculate the Z-score and probability for a raw data point (x) in a normal distribution.
Z-Score: N/A
P(Z ≤ z): N/A
See the data ranges for 1, 2, and 3 standard deviations from the mean in a normal distribution.
Enter a mean and standard deviation to see the ranges.
To find the union and intersection of two **independent** events.
P(A ∩ B) (A and B): N/A
P(A ∪ B) (A or B): N/A
Provide any 2 values to calculate the rest of the probabilities of two **independent** events.
pA: 0.5000
pB: 0.5000
pA': N/A
pB': N/A
pA and B: N/A
pA or B: N/A
pA delta B: N/A
p neither: N/A
Calculate the probability of events occurring in a series of independent trials.
P(All Occur): N/A
P(None Occur): N/A
