a = -3/2

Step-by-step explanation:

You can set x=0 and solve for y to find the y-intercept in each case.

Paladinen [302]

Answer: 1/1024

Step-by-step explanation:

When a fair coin is flipped the coin would show either head or tail meaning only 2 outcomes are possible. So, getting an head means 50% chance or 1/2 chance.

Now, it means chance for 10 times head every time= (1/2)^10

Chance= 1/1024

Chance= 0.00097
