What is the probability of Aor B if and B are disjoint?
1
Its simple what are disjoint events?
Two events are disjoint if they cannot occur together. In set terms, their intersection is a null set.
Can independent events be disjoint?
No.
How do you find the probability of two distincve events?
It depends on whether or not the events are independent.
Two disjoint events in which one or the other must occur are called?
Complements or complementary events
What is a disjoint events mean?
In probability theory, disjoint events are two (or more) events where more than one cannot occur in the same trial. It is possible that none of them occur in a particular trial.
Event A has probability 0.4 event B has probability 0.5 If A and B are disjoint then the probability that both events occur is?
If two events are disjoint, they cannot occur at the same time. For example, if you flip a coin, you cannot get heads AND tails. Since A and B are disjoint, P(A and B) = 0 If A and B were independent, then P(A and B) = 0.4*0.5=0.2. For example, the chances you throw a dice and it lands on 1 AND the chances you flip a coin and it land on heads. These events are independent...the outcome of one event does not affect the outcome of the other.

Addition rule for probability of events A and B?
If they're disjoint events: P(A and B) = P(A) + P(B) Generally: P(A and B) = P(A) + P(B) - P(A|B)

Can independent events be disjoint?
No.
Are two disjoint events always complementary?
no
How do you find the probability of multiple events?
The answer depends on whether or not the events are independent.
How do you find the probability of two distincve events?
It depends on whether or not the events are independent.
How don you find the answers to simple independent events?
you find the probability

If dealt one card from a standard 52 card deck what is the probability of being dealt an ace or a 9?
Aces and 9s are disjoint events, so the probability of either is the sum of the probabilities of each. P(A or 9) = P(A) + P(9) = 1/13 + 1/13 = 2/13
