IF P(A)=1/3, P(B)=2/5, and P(AuB)=3/5, what is P(A^B)?

Bumek [7]

The probability of the union of two events is the sum of their probability, minus the probability of their interserction:

$P(A \cup B) = P(A) + P(B) - P(A \cap B)$

If we plug the known values into this formula, we have

$\dfrac{3}{5} = \dfrac{1}{3} + \dfrac{2}{5} - P(A\cap B)$

From which we can deduce

$P(A\cap B) = \dfrac{1}{3} + \dfrac{2}{5} - \dfrac{3}{5} = \dfrac{2}{15}$

So, the probability of $A \setminus B$ is a bit less than $P(A)$ , we have to take away all events that belong to B as well:

$P(A \setminus B) = P(A) - P(A\cap B) = \dfrac{1}{3} - \dfrac{2}{15} = \dfrac{1}{5}$

What is 2 1/2 divided by 1/3

olga nikolaevna [1]

Answer:

7 1/2

Step-by-step explanation:

2 1/2 ÷ 1/3

Change the mixed number to an improper fraction

2 1/2 = (2*2+1)/2 = 5/2

5/2 ÷ 1/3

Copy dot flip

5/2 *3/1 = 15/2

Changing back to a mixed number

2 goes into 15 7 times with 1 left over

7 1/2
