Answer:

$7$

Step-by-step explanation:

So we have the expression:

$|3x-1|$

And we want to evaluate it for x=-2.

So, substitute -2 for x:

$|3(-2)-1|$

Multiply:

$=|-6-1|$

Subtract:

$=|-7|$

The absolute value of a negative is positive. So:

$=7$

And we're done!

If two siblings are boys, what is likelihood that the third sibling will also be a boy

melamori03 [73]

The is a 50% chance of being a boy or a girl.....previous siblings do not matter. Every child is an independent event. So even if u had 2 siblings that were boys, the result of the next one being a boy is still gonna be 50%...just as the odds of it being a girl, is 50% as well.
