Question

How many heads would you expect if you flipped a coin twice? First, fill in the table below with the correct probabilities. Hint: The sample space for flipping a coin twice is {HH, HT, TH, TT}. A = B = C =

Answer 1

a= 1/4 or .25 b=1/2 or .50 c=1/4 or .25

the expected value fro the number of heads is 1.

Explanation:

this is for edge

Answer 2

Probability of getting heads in flipping a coin twice is
`(3)/(4)`.

Explanation:

We have been given a case of coin flipped twice.

The sample space for flipping a coin twice is: {HH,HT,TH,TT}.

`Probability=\frac{\text{Favourable outcomes}}{\text{Total number of outcomes}}`

`Probability=(3)/(4)`

So, probability of getting heads in flipping a coin twice is
`(3)/(4)`.
