55% of college freshmen are women. If you pick 4 freshmen at random. What's the probability they are all males?
1 answer:
probability they are all males is 0.041
<u>Step-by-step explanation:</u>
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

Y+4<u><</u>9
subtract 4
y<u><</u>5
y is smaller than and equal to 5
so you shade from 5 to the negative end to infinity (to the left) and shade the 5 to show that it is included (attachment says A)
6 less than (-6) 2 times a number (2 time x) is greater than (>) 8 (8)
-6+2x>8
add 6
2x>14
divide 2
x>7
so
x is bigger than 7
shade from 7 to the positive end to infinity (to the right) and don't shade 7 but put a circle around it to show that it is not included (attachment says B )
