Answer:
use demos
Step-by-step explanation:
An addition sign between 978 and 842 would make the equation true!
The more observations you make the closer and closer the experimental probability will approach the theoretical probability. In this case the theoretical probability is:
P(HH)=(1/2)(1/2)=1/4
So in 105 trials one would expect to get two heads:
105(1/4)=26.25 times.
