The 0 14 is because the probability of a and b is the probability of a times the probability of b or 0 20 0 70 0 14. Formula for the probability of a and b independent events.
Probability With Discrete Random Variable Example Video Khan Academy
Probability of a or b 1 of 3 if events a and b are mutually exclusive then the probability of a or b is simply.
How to get the probability of a and b. All you do is multiply the probability of one by the probability of another. If the probability of one event doesn t affect the other you have an independent event. If a and b are independent a and b are two events.
What is the probability of rolling a die and getting either a 1 or a 6. If a and b are independent then the probability that events a and b both occur is. P a or b p a p b.
P a and b p a x p b. P a and b p a p b.
