Probability of having at least 1 boy = 1 - the probability of having ALL girls.

P(5 girls) = (1/2)⁵ = 1/32

P(At least 1 boy) = 1 - 1/32 = 31/32

Answer: 31/32

What number is 70% of 120?please give the equation with x

MA_775_DIABLO [31]

You can set up this equation as:
$x = 0.7(120)$

Because remember, 70% is equal to 0.7 and x represents the unknown value. So, let's just solve it:
$x = 0.7(120)=84$

So, 70% of 120 is 84.
