ANSWER

P(B \: and \: C) =  \frac{1}{6}


EXPLANATION

Recall that,

P(A \: and \: B)=P(A) \times P(B)

But we were given that,

P(A)= \frac{1}{8}

and

P(A \: and \: B) =  \frac{1}{12}


We substitute these values into the above formula to obtain,


\frac{1}{12} = \frac{1}{8}  \times P(B)



This implies that,

\frac{1}{12}  \times 8=8 \times  \frac{1}{8}  \times P(B)



This simplifies to,

P(B) =  \frac{8}{12}


P(B) =  \frac{2}{3}


So we can now find
P(B \: and \: C).



We use the same formula again,

P(B \: and \: C) = P(B) \times P(C)
We substitute the values to get,


P(B \: and \: C) =  \frac{2}{3}  \times  \frac{1}{4}
We multiply out to get,


P(B \: and \: C) =  \frac{1}{6}

3/7 = /12<br> How do I find the answer
guajiro [1.7K]
Cross multiply the denominators by the numerators. In other words, 12 times 3 and 7 times x (x, being our missing number).
We end up with 36 and 7x.
Divide both sides by 7.
36/7x = 5.14
x = 5.14
Hope this helps!

Example 5
Svetllana [295]

Answer:

1/2*6(12+x)=12*x

1/2*(72+6)=12x

36+3x=12x

36=9x

4=x

Step-by-step explanation:

Check that x=4

1/2*6(4+12)=12*4

1/2*(24+72)=48

1/2(96)=48

48=48

So x=4 is the correct answer

Brian buys 5 cookies and 1 bottle of water. The total cost is $8.75. If the bottle of water costs $1.25, which equation can be u
lubasha [3.4K]

Answer: $1.50/cookie

Step-by-step explanation:

Cookies = x

Water = y

5x + y = $8.75

y = 1.25

Plug in y-value into equation:

5x +1.25 = 8.75

5x = 8.75 - 1.25

5x = 7.50

x = 7.50/5

x = $1.50 for 1 cookie.
