25 out of 65 people are wearing red, if there are 65 people at the party and only 25 are wearing red you would find the percentage by dividing 65 by 25 which equals to 2.6%
i hope this is correct im not great at math but i hope this helps
The components operate independently, so the probability of "total" system failure is the same as the product of each probability of component failure. That is, if
denotes the event that component
fails, then
The
are independent and identically distributed, so
for all
. So
Your order:
2r + b = $8.40
3r + b = $9.35
Sorry, if I kept you waiting. It took me awhile to figure it out.
