Answer:
Probability of getting heads in flipping a coin twice is [tex]\frac{3}{4}[/tex].
Step-by-step explanation:
We have been given a case of coin flipped twice.
The sample space for flipping a coin twice is: {HH,HT,TH,TT}.
[tex]Probability=\frac{\text{Favourable outcomes}}{\text{Total number of outcomes}}[/tex]
[tex]Probability=\frac{3}{4}[/tex]
So, probability of getting heads in flipping a coin twice is [tex]\frac{3}{4}[/tex].
Answer:
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.
