A balanced coin will have 50:50 chance of showing either head or tail. In this question, you are asked the probability to find the first head after two tosses. That means the toss result should be:
1. tail = 1/2 probability
2. head = 1/2 probability
Previously you are tossing the coin 10 times and obtain zero head. But this previous 10 tosses result should not influence your probability in the 11th and 12th toss. The chance will always be 50:50 no matter how much the tosses count. So the probability should be: 1/2 * 1/2= 1/4
Answer:
C-f(x)=1.5x
just took the quiz and 3/2 reduces to 1.5
The right answer to this is (0,-5). If you substitute the points into the equation, it will give the answer 10.

The points (0,-5) satisfy the equation because both sides of the equation is equal to 10.
Answer:
6.9282
step by step:
=( 2 x 24 )1/2
= ( 48 )0.5
= 6.9282
