55% of college freshmen are women. If you pick 4 freshmen at random. What's the probability they are all males?

probability they are all males is 0.041

Step-by-step explanation:

Here we have , 55% of college freshmen are women. If you pick 4 freshmen at random . We need to find What's the probability they are all males . Let's find out:

Probability to have women is 55 % i.e. 0.55 so for men is :

⇒

⇒

Now , 4 persons are randomly chosen and we need to find probability to have all 4 males that will be :

⇒

⇒

⇒

Therefore ,  probability they are all males is 0.041

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
