If your asking what the price of something is, that was originally 29.99, and has been marked down by 33.33%, the easy way to do this is to take 30 and multiply it by 1/3, resulting in 20. The proper way is to take your calculator and multiply 29.99 by 0.333, resulting in roughly 9.98, meaning the price you pay is 20.00. Either way, your still going to pay $20 for the item.

Answer:

0.25

Step-by-step explanation:

Given that a recently married couple are planning to have four children. They are equally likely to have a boy as well as a girl.

Let X be the no of boys the couples have. X has two outcomes with p = 0.5

X is binomial with n = no of trials = 4 and p =0.5

the probability that they will have three boys and one girl

= $P(X=3)\\=4C3(0.5)^3(0.5)\\= 0.25$

Reqd prob = 0.25

Let g(x)=2x and h(x)=x^2+4 <br><br> (g o h)(0)

sweet [91]

Answer would be 0 because whatever you get when you plug in g&h in the equation you have to multiply that by 0. And a number multiplied by 0 is always 0.
Hope this helped. Have a great day!
