the power (or exponent) of a number says how many times to use the number in a multiplication. It is written as a small number to the right and above the base number. In this example the little "2" says to use 3 times in a multiplication: 2x2x2= 8

P(A)= .50 P(B)=.80 P(A and B)=.20 what is P(B/A)
Reil [10]

Answer:

Final answer is P(B|A)=0.40.

Step-by-step explanation:

Given that P(A)= .50, P(B)=.80 , and P(A and B)=.20.

Now we need to find about what is the value of P(B/A).

So apply the formula of compound probability :

P(A and B) = P(A)*P(B/A)

Plug the given values into above formula

0.20 = 0.50*P(B/A)

0.50*P(B/A) = 0.20

P(B|A)=\frac{0.20}{0.50}

P(B|A)=0.40

Hence final answer is P(B|A)=0.40.

The 2 angles form a linear pair and angles that form a linear pair have a sum of 180 so

10x + 15 + 5x = 180
15 + 15x = 180
180 - 15 = 15x
165 = 15x
11 = x
