First we find the circumference
c=2pir
r=3
2pi3
6pi=c

then find out how much of the circle is 50 degreese
50/360=5/36
6pi times 5/36=5pi/6=aprox 2.62

it should be 5pi/6

Then you multiply 3 twice as well which gives you 9, so now you add 1/9+9=82/9

Jack has a fair coin. He tosses the coin four times. What is the probability that Jack gets heads, then heads, then tails, and t
Tcecarenko [31]
As you have a 1/2 chance of getting what you want when you flip the coin, to get heads, heads, tails, tails will be 1/2 x 1/2 x 1/2 x 1/2. Working our way down the line, 1/2 x 1/2 = 1/4, 1/4 x 1/2 = 1/8, and 1/8 x 1/2 = 1/16. Jack will get heads, heads, tails, tails 1/16 of the time.
