Question

Maria flips a dime four times. What is the probability that she will get at least one head?

Answer 1

I know for sure it is 1/2
Would I multiply 1/2 4 times?

Answer 2

How many sides are on a coin?

Answer 3

2.

Answer 4

That means she has a 50% chance every time she flips a head

Answer 5

If she flips a coin 4 times she still has a 50-50 chance of getting a head

Answer 6

So it would be 1/2*1/2*1/2*1/2 =1/16?
Is that right

Answer 7

at least one head means
one head and one write + two head no write
1/2*1/2 +1/2*1/2=2/4=1/2

Answer 8

you could also find the probability of "no heads" and subtract it from 1

Answer 9

yeah hehehe

Answer 10

\[1-\left(\frac{1}{2}\right)^4=\frac{15}{16} \]
