Answer:
Step-by-step explanation:
sin( )
using the sides of the 30- 60- 90 triangle
with legs 1, and hypotenuse 2 , then
= 30° and
sin30° =
By sine rule,
sin40/45= sin<B/60
Angle B= 59.0
Remaining angles are 59.0 and 81.0
Answer: The probability is about 0.2%.
The probability of flipping heads one time is 0.5, 50% or 1/2.
To flip heads 9 times in a row, we have to multiply 1/2 by itself 9 times.
(1/2)^9 = 1/512 or about 0.2%
It should only happen once every 512 times.
