If ​P(A)=0.9​, ​P(B)​=0.1, and A and B are​ independent, find​ P(A and​ B).
sweet [91]

According to the given statement;

If ​P(A)=0.9​, ​P(B)​=0.1, and A and B are​ independent, ​ P(A and​ B)=0.09

<h3>What is probability of event?</h3>

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a proposition is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty. The likelihood that an event will occur increases with its probability. A straightforward illustration is tossing a fair (impartial) coin. Since there are no other possible outcomes and the coin is fair, the odds of both the outcomes, "heads" and "tails," are equally likely to occur. As a result, the probability of either outcome is half.

<u>According to the given value;</u>

P(A) = 0.9

P(B) = 0.1

A and B independent;

We know that independent

P(A∩B) = P(A) · P(B)

             = (0.9)*(0.1)

             =0.09

P(A∩B) =0.09

hence, If ​P(A)=0.9​, ​P(B)​=0.1, and A and B are​ independent, ​ P(A and​ B)=0.09

Provide the answer as a decimal​
olga55 [171]

Answer:

0.55

Step-by-step explanation:

The right-hand column of the table gives us the probabilities of the probability function. We know from elementary probability theory that the "probability" of any event(s) happening would be from 0 to 1 inclusive.

The total probability of all events would add up to 1. So, we look at the probabilities given for each even, x, and add them:

0.29 + 0.09 + 0.03 + 0.04 = 0.45

All of these probabilities and the probability at x = 2 (the unknown) would add up to 1, so we can say:

0.45 + probability (x = 2) = 1

Probability at x = 2 = 1 - 0.45 = 0.55
