Mathematics

AlexFokin [52]3 years ago
5 0

Answer: the value of P(B) = \dfrac{1}{3} .

Step-by-step explanation:

If A and B are two independent events, then P(A and B)=P(A) x P(B)  (i)

Given the following probabilities : P(A)=\dfrac{1}{2},\  \ P(\text{A and B})=\dfrac{1}{6}

To find : P(B) such that events A and B are independent

Put all values in (i), we get

\dfrac{1}{6}=\dfrac{1}{2}\times P(B)\\\\\Rightarrow\ P(B)=\dfrac{2}{6}\\\\\Rightarrow\ P(B)=\dfrac{1}{3}

Hence, the value of P(B) = \dfrac{1}{3} .

Larry bought 12 containers of pasta salad for a school picnic. Each container held the same number of ounces of salad. Students
tester [92]

Answer:

12 p - 8 p,  4p ( 3 - 2)

Step-by-step explanation:

p = equal the number of ounces of pasta salad in one container

then 12 × p = 12 p in 12 containers

the students finished the pasta salad in 8 containers which equals = 8 p

the number of ounces of pasta left = 12 p - 8 p  

b) using the distributive property for example a ( b + c) = ( a×b) + (a ×c)

12 p - 8 p = 4p ( 3 - 2)

Evaluate the following expression, when n=-3 and r=-8<br> −5 + 3(−2r + 4n) <br> Pease answer ASAP
Hunter-Best [27]

Answer:

-8

Step-by-step explanation:

Given that,

n = -3

r = -8

Now we have to find the value of the given expression.

For that, you have to replace n and r with ( -3 ) and  ( -8 ) respectively.

Let us solve now.

−5 + 3 ( −2r + 4n )

-5 + 3 ( -2 × -8 + 4 × -3 )

-2 ( 16 - 12 )

-2 × 4

-8

Let me know if you've any other questions. :-)

Convert r1,200 billion to million please help me out
Anika [276]
This is just converting billion to million, vice-versa.
1 million = 0.001 billion

1,200 billion = 1,200,000,000,000 
So once it is converted, the answer will be, 
1.2 x 10^15 million.
